High End Preamp from the late 70's. It's the improved "B" version of the Model 3250. Very fine phono section.
The model 3250B incorporates a built-in MC (Moving Coil) phono preamp, a feature rarely seen in vintage audio pieces. Exceptional user comfort with all sounded controller options.
Sounds and looks good in mint shape.

Der 3250B Vorverstärker markierte Ende der 70er den High End Stand der Dinge bei Marantz. Das Modell mit ausgezeichnetem Phonoeingangsmodul und war bereits für MC-Tonabnehmer vorbereitet, eine zu dieser Zeit noch selten gesehene Ausstattung. Der Bedienungskomfort einschliesslich der Klangregeloptionen ist überragend. Die "B" Version markierte den Nachfolger den Modells 3250. Dieser Klassiker im Mint-Zustand sieht so gut aus, wie er klingt.

It's working but need some serious restoration. Design Dieter Rams 1959.
Testing Magic Lantern firmware and audio gear for HD video recording on the Canon 5D Mark II. The 5D has a poor built in microphone and a similarly poor microphone jack, no audio meters, and nasty auto gain (think noise). In order to move around freely with the camera and get decent audio you have to use some sort of preamp. In this case it's a juicedLink CX231. There are two microphones attached because I was testing to see which one worked better. The mics are the Sennheiser MKH-50 and ME64. (I will report back which one works better but my guess is with the low quality signal path they will be fairly similar, though the MHK-50 is normally superior.)
I'm using the Magic Lantern firmware hack for the Mark II because I needed the audio fixes (auto gain disable & audio input meters). So far it has worked as advertised. The annoying thing is also the reassuring thing with this software: It has to be reloaded from the CF card into RAM every time you turn on the camera, which means your camera reverts back to the Canon firmware every time. I'm not a fan of these kinds of hacks for expensive hardware - mostly because I cannot fix it myself should it screw up the device. More on Magic Lantern: magiclantern.wikia.com/wiki/Magic_Lantern_Firmware_Wiki
Mini review of the juicedLink CX231: (1) It is strong but crudely built, meaning it was not 'designed' externally. There are several sharp edges and it is larger than need be. (2) So far, it sounds OK but I'd have to send it into a decent A/D converter to be able to tell much. (3) No headphone jack, which is ridiculous considering the 5Dmkii has no audio meters or headphone jacks itself.

My first self-built amplifier is finally completed (except for some possible improvements on the case externals, e.g. the text is still hand-written).
This thing works as a headphone amplifier and a valve pre-amplifier for speakers. It can also work as a passive pre-amplifier and/or crossfeed processor when powered off. There are two switchable inputs and outputs (the headphone socket on the front panel + two sockets in the rear panel).
The original SOHA II amplifier design is by Alex Cavalli. I've made some changes to the power supply (added some line filtering circuitry). The optional (completely bypassable) crossfeed effect is a simplified version of the CORDA CROSS-1 with some component value changes and toggles instead of rotary switches. I like toggles.
I've wanted to build a valve amplifier for a long time, mostly because I think they are really cool (despite running quite hot) and solid-state amplifiers aren't very interesting to me as I can't hear any difference between them (other than imaginary). I'm very happy with the result—with headphones the sound is pleasantly non-tiring and open, and as a pre-amp it gives more “kick” compared to my passive volume control (although at the expense of a higher noise floor).

Not so coldly charted it's really just a question of your honesty, yeah, your honesty.
One likes to believe in the freedom of music
But glittering prizes and endless compromises
Shatter the illusion of integrity

So much music today ( prepares old man "back in my day voice...." ) to me is "expendable". I guess it's always been this way though. So many songs put out in a year, a small percentage of those are heard numerous times by a decent amount of people, a small percentage of those will "stand the test of time", etc. I guess I'm a music snob.
Disclaimer: non-bass heads will find the following boring and glad that I saved them 35 seconds of their life with advance notice. If you play bass please continue reading...I made a few basses through the years, but this is the only one that "lived". The electronics cost waaaaay more than the bass ( Bartolini pickups, Aguilar 18 volt preamp, custom routing, changed a jazz bass to 4 knobs splitting the preamp, relocating the input jack, etc ) but that was part of the adventure of building it. I wasn't sure exactly how it would sound. A fantastic reggae bass ( so low you'll go sterile ), not so good at funk ( which is what I play most of the time ).

Another durable preamp tube. Been using this tube for over 20 years now and still performing at its best.
Setting up my old LP player was not easy or simple!
First, I had to dust the cover then checked the wires connection to the cartridge. Next, ensuring the perfect balance of the tonearm, adjusting the stylus for correct tracking force… then connecting the player to the phono stage, photo stage to the preamp, preamp to the amp then the amp to the speakers. The time spent was however well worth it, the sound was so sweet and melodious

A home-built integrated stereo tube amp (actually, a transistor-tube hybrid amp) in the style of an early 1960's household hi-fi set. The preamp and phono preamp sections use a tube circuit based on a classic design, while the power amp modules use an all transistor open source design called the "JLH 1969". Check out www.alvenh.com/misc-projects/tubeamp for full story.
This JJ ECC803S Gold Pin is my favorite new production preamp tube. Been using this most of my listening time since 2018.
Another beauty shot of the SP-25. It's a work in progress...Shown on the side is a custom preamp and headphone amp.
with this revision, we now have a matching psu board. cabling is simplified and solderless (IDC jacks and headers). analog voltage is fed into the board via one cable and 2 digital 5v via another (cpu and relays).
I had a rear panel leftover from another project and used those panel-mount rca jacks instead of the board-mount ones that fit properly to the preamp board.
the power button is not yet wired up (so far, I've not missed not having it work) ;)
interior-wise, its a pretty clean install. once I have new rear panels that match this board's jack layout, it will look even better.

The Best AT-LP120USB in the world.
USB Preamp removed
Platter and plinth Dampened
Custom tonearm armboard created
Poorly designed stock tonearm replaced
Technics Supermat 1/4" and headshell added
RCA Jacks installed
Custom made, low capacitance cables
Audio Technica AT-150MLX cartridge
TTW center weight added
Extra isolation
New PRO-JECT USB Preamp installed
Low capacitance cables installed
Can it now compete with the legendary Technics SL-1200MK2? NOPE. This project was for educational purposes only and is not recommended. The end results are great, but the cost to mod the 120 could have been spent on a real 1200MK2 which is superior in every way.
If AT could rectify 4 problems with the LP120USB, then it would be a great entry level table for home use. 1 is make the antiskate work. 2, lower the arm assembly so VTA can be properly adjusted. 3, include a rubber mat to reduce platter noise and vibration. 4, get the W&F down by half.
I decided to put together a new MM phono preamp to run my AT-440MLa cartridge. The preamp has adjustable gain and input load, so it should be a good match for most MM cartridges.
A photo I took in late 2013, not long after I'd completed my home microphone setup. Compare it to the way the same space looked a month earlier. I originally put it together for voice chat in online video games, but I ended up also using it to do my radio show from home.
The EV 309A shockmount proved to be too problematic to keep using. The rubber band bits fail too regularly and are insanely expensive to replace.

My finished laser-cut chassis. I'm happy with how it turned out.
This is the LCDuino audio preamp that I designed and built (working with Ti Kan of AMB labs for pcb design and fab).
This device is a remote-controlled audio preamplifier that includes input/output line selection, motorized volume control knob (control element, only), a relay-based R2R style precise analog attenuator, low-noise linear discrete (for analog) power supplies and line-buffer amps and using hitachi standard 2x16 LCD displays, all controlled by my open-source Arduino code.
On the left, you'll see a board with a row of relays. That is the attenuator or volume-control part. Below it is a mating board that uses much of the same control logic but it's relays switch inputs and outputs.
On the right are two power supplies; an analog discrete dual tracking 12v (sigma22) and a small linear 7805 style 5v.
In the middle are 2 small alpha20 discrete analog line buffer/drivers.
Front of chassis is the LCD display with the LCDuino mounted behind it 'backpack style'. The LCDuino runs Arduino application code that gives this hardware all the remote control and user interface functions. The firmware is open-source and end-users can easily modify it if needed.
