Calling Ampeg V4BH users!
Could someone with experience please tell me what value the Gain potentiometer on a Ampeg V4BH Classic Series from 2003 is? Someone told me it's a 1Meg Audio, but my technician says that's unlikely. I need someone with hands on experience to back me up so I can force him to do what I want him to do with my equipment.
The original pot is faulty, btw.
THANKS a 1.000.000 times beforehand!
PD: If anyone has the schematics I'd be thrice as happy! :D
Uh, it should be printed on the pot!
Alternate method is to desolder the pot and measure the resistance between terminals 1 and 3 (even if the pot has a bad wiper, this will work unless the pot's carbon track has been damaged).
The schematic shows 1M A by the way for the Gain (P1). Master volume is 50K linear, maybe that's what the tech was referring to.
The part number is 70-105-12. Call Loud parts at 1-800-898-3211 ext. 1623.
There's no value on the pot, only a code. As I don't know the pot manufacturer I cannot see what that code means.
So, 1meg Audio, as I've been told. Is this like a standard measure for Ampeg Gain controls?
PS: I cannot call US, I'm located in Spain, EU.
why don't you just measure it? (or is it broken)
So, my tech thought he knew better and put a different value pot in the Ampeg... Now it sounds wonderful but at 1/100th of the volume I'm used to from it >.< I suspect he put 1K Audio, insted of the 1M Audio I asked for.
Sooooo, back to the tech it goes... This time I'm ordering the spare part!
Where do you get authentic Ampeg spareparts in Europe?
Maybe you should think about using a different tech.
