Hi guys,
I am trying to replace two 1960's Hunts 50V 2500uf large can aluminum capacitor that are in a 1964 transistor Vox T.60 bass amp. The capacitor is about 4 inches long and 1 and 3/8 inches in dia.
I see on ebay a Mallory 2500uF 50V Large Can Electrolytic Capacitor CGS252U050R4C3PH for sale of the same size and near the same color.
I can not seem to find a data sheet on the old Hunts capacitor or the new Mallory.
In today's world I ASSUME there is no need for such a large form factor electrolytic capacitor and I could use a smaller cap and "hide" it inside the old Hunts can.
Am I missing something??
Cheers,
Billy
BTW: All of this is part of trying to rebuild a 1964 Vox T.60 bass amp. This was the first transistor amp every built by Vox and was a serious failure. It is unstable and eats output transistors for breakfast...lol
This is a comment someone on another forum made. "This T60 amplifier circuit must have a very high THD because it use a driver transformer, bad bias of the output transistors (probably class B) and has no feedback"
The idea is to return this amp to as close to original as I can and not to address the design flaws. Well...I guess, at least at this point.
