nice job Bouquet ! what do you think about the grey waterproof Sic Safco caps ?!

 

[Bouquet]

Hi Coresta ,

I don't think it's Sic Safco ; the brand printed on it is "Micro" .
They are 50 uF / 200 V and very well suited for cathode decoupling. In my opinion they are more neutral even as Black Gate and more rare too. very hard to find.

Like these ?! they were made for telephone/television equipments , i think they can last a loooong time

32 MF????????????

Depends on date of manufacture. There was a time in the 50s when MFD was often used, presumably because the "micro" sign was not generally available in the relevant printing processes.

Edit: Couldn't even bring up the mu-sign now!

 

[Speedskater]

This mu-sign " µ " ?
It's [alt] 0181

 

[Johan Potgieter]

Thanks Kevin.

Something the matter with some of my "alt" functions. Will get my PC expert to come and debug (he usually also takes me to dinner).

Not exactly an amplifier...

This is based on the tube synth articles written by Eric Barbour. The dark box is the external power supply for +/-150v and heater voltage. The small silver panel is a MIDI to CV converter to drive the oscillators from either a keyboard or computer.

it really looked like MEGA
but then a 32 MegaFarad cap would be as big as a building I imagine,,,

My [alt] does not work either

Den var kjempefin!

So few SE-amps are built around KT88/6550 ....

An externally hosted image should be here but it was not working when we last tested it.

It uses a Novarria transformer!! I'd never thought they could make it out of italy!!
