Re: Elka - Panther 100 (1960) - germanium organ [schematic]

Really? They would at least require rebiasing, do the trimpots allow for this flexibility? Like I said, haven't got the thing on the bench yet, but the main problem are a mass of noise, independent of the volume control. I am hoping to fix the main amp or upgrading it (I have two nice small 25W soli...

Elka - Panther 100 (1960) - germanium organ [schematic]

Not a stompbox at all, but maybe many have been hacked to be sold off for the germanium transistors. A friend bought this beauty for near to no money... and got the schematic from a document peddler on the web.

Re: Davoli Krundaal - Amplificatore D531T [schematic]

In the first stage, I wanted to get it working again and not do any mods, just get the tremolo tremming again. This amp has been worked on before. One of the two can capacitors has been replaced and much of the power section was redone... This surprised me because there the chassis screws were still...

Re: Krundaal Davoli - Amplificatore DTE-531T [schematic]

I wasn't going to ... but I did. Paid too much, but what do you expect trying to wrestle a pink amp from a very nice lady...
it's very sensitive to high output humbuckers
the tremolo doesn't work.



Just a demo, no work done yet...

Re: Dr. Z - Z-Wreck [schematic]

Almost 100% VOX AC30. Some time ago some panties got waddled on facebook over the 500pF coupling cap. I remarked that the 2.2nF after the first stage is the place to look for fattening up the tone on that amp. Buddy stated "I seen coupling caps as low as 500pF in Vox etc.." So here it is, but my qu...

Davoli Krundaal - Amplificatore D531T [schematic]

It's cute and pink and it's probably a accordion amp, but got kind of intrigued by the tube setup: 1 x 12AX7 or ECC83 2 x ECL82 - which is a triode and pentode in one package! 3 tubes: 2 gain stages, tremolo, phase inverter and 10W output 107082877_500680150703840_1322112746295876675_n-2.jpg 1069925...

Ben
Are you saying the Sustain Module is different from the Supasustainer?
Might well be the case, but please share your evidence.
