Today on #JencenMakes

The Compton Melotone (pronounced like Monotony)

This example is actually a Compton 356 (I think. There's so many numbers) that has been gently transferred from its 2 manual and pedal case to this fuckin' thing.

On the rear side you have the test panel on the left. Then the boards behind that are the "Time Constant" circuits that decide the "envelope" of the sound. Think Attack/Decay.

To the bottom are the voicing resistors.
These decide which sine waves are added together to produce a complex waveform. It's pre determined on this unit instead of there being a set of stop tabs.

At the very bottom are the chassis for the power supply to provide 500Vdc to all this, the empty spot is the amplifier which is out for poking at. And then the pedal contact assembly.

On today's episode of #JencenMakes

This fuckin' thing!
A Bush SUG23 Superheterodyne gramophone receiver Circa late 40's early 50's.

Am not gonna go into how a SuperHet works - @TechConnectify did a fantastic runthrough of that here! https://www.youtube.com/watch?v=hz_mMLhUinw

This is for my FoxShape to have some tunes in his room whilst maintaining his late 1800's aesthetic ^_~

Sadly something has "Done a poo" all over the inside of the cabinet.

Powering up you get the heaters on the valves but no hum or noise of any kind implying the HT has gone somewhere!
Dunno where. Some sort of holiday I guess!

Sooooo....... I'm gonna annoy a few people by ripping out its guts and installing some modern gear.
Am not going to bin the tuner/amp chassis as it's all valve based and interesting/important to the museum story of making wiggles. And at some point I'll restore it and do a writeup/video about it.

For now though. Follow this thread for more info and blasphemy!!!

Don't worry. the case won't be harmed!
