Minifigs have plenty of guitars these days but not much to play them through! How about a classic English class AB tube amplifier?
Good Morning ! (or day)
If you had tough Friday night you probably will need one of this amplifier, to wake you up So I'm going straight to StudioSoundLab to drop those photo. Maybe I will wake up

I sold my old Jazz Bass and is now waiting for a new Bass to arrive.
Until then my old amplifier is quiet.
ISO 800 - 1/40 sec - f/1.6 - 30 mm
1975
This item is originally my first first stereo amplifier bought in 1975. I've got it back from my school friend now. As a collector I'm very happy because it is still as good in shape as I sold to my friend around 1980.
The amp provides 55 watts pc and that's enough for rocking the whole house and neighbors. A three-stage impedance matching for phono input is something special. Two phono inputs were already standard at Technics amplifiers.
Testing, Testing, ... BANG!!!
Nondestructive testing
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.[1] The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.[2] Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing,[1] and low coherence interferometry.[3][4] NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.[1] Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography.
Methods[edit]
NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples. This includes some kinds of microscopy to examine external surfaces in detail, although sample preparation techniques for metallography, optical microscopy and electron microscopy are generally destructive as the surfaces must be made smooth through polishing or the sample must be electron transparent in thickness. The inside of a sample can be examined with penetrating radiation, such as X-rays, neutrons or terahertz radiation. Sound waves are utilized in the case of ultrasonic testing. Contrast between a defect and the bulk of the sample may be enhanced for visual examination by the unaided eye by using liquids to penetrate fatigue cracks. One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part. Thermoelectric effect (or use of the Seebeck effect) uses thermal properties of an alloy to quickly and easily characterize many alloys. The chemical test, or chemical spot test method, utilizes application of sensitive chemicals that can indicate the presence of individual alloying elements. Electrochemical methods, such as electrochemical fatigue crack sensors, utilize the tendency of metal structural material to oxidize readily in order to detect progressive damage.
Analyzing and documenting a non-destructive failure mode can also be accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture some non-destructive failures.[5] After the failure the high-speed camera will stop recording. The capture images can be played back in slow motion showing precisely what happen before, during and after the non-destructive event, image by image.

Smoking 💨 but not a cigarette 🚬; instead it’s a mini-amp 🔊 powered by a 9V battery🔋. Just plug in 🎸 at the bottom & you’re ready to go 🚦! Just slip in your pocket & you’re off to the races 🐎!

Red velvet cake with white Belgian chocolate truffle filling inside guitar (30 servings), and milk chocolate cake with dark Belgian chocolate truffle filling inside the amplifier (60 servings).
Everything is mapped to size and proportions in Adobe Illustrator. The guitar is life size, the amplifier is 2 times smaller the original. Labels and design elements are recreated in vector and printed on Icing sheets.
All edible, except real strings.

Strobist: SB-700 / 16 mm at 1/128 with softbox - camera left - triggered by on camera flash
1979
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.
