There was something wrong with my first edit, in my opinion the light was too white.

So I edited it again by giving it a photoshop photo-filter.

After several tries it turned out I did like a sepia at 100% best... this is the result.

as it looks!

Minifigs have plenty of guitars these days but not much to play them through! How about a classic English class AB tube amplifier?

Marshall JCM800

Does this one go up to 11?

Taking a photo of my Mustang 2 Amp settings is probably the only way they will be remembered by me.

Tube in high end audio headphone amp.

Room B ass. sound lab Bologna

one that I built from scratch in 1980 using experience gained from repairing stereo equipment for many years. Still works perfectly to this date. I built at least two others, they have held up too. Boards on the right are LED level indicators for output.

Good job they are only EL84’s in there. EL34 thru KT88’s are cooking territory. The Blackstar HT20 RH is a lovely sounding amp, especially through the Celestion greenback speaker

On the far right, on the grill, it says: "Marshall."

Well, it is an amplifier, in a sense.

It´s an old, forgotten, El Camino, at least.

I have just found Alex is not only an increadible photographer, but also a crazy music lover. This is what I saw at his lab. I did not know audio gears could be so sophiscated.

I pulled an old amp out of the cupboard and after replacing a couple of the tubes it worked fine. The blue fluorescence from electrons on the envelopes may indicate a problem, I am not sure. The speakers are my own design/build using SEAS and Bohlender Graebner drivers.

Get right in there to see that amtrak logo, yes, i travel through time daily. ∆

This project is about a TPA3001D1 audio power amplifier. We built and tested this amplifier as a more efficient alternative for the TDA2030 power amplifier.

Additional details and all the project files are available at jayakody2000lk.blogspot.com/2021/11/tpa3001d1-power-ampli....
