I need an ampeg V-3 V-7 japanese design pre-amp schematic
Hi
I am new to this forum but I have been reading and getting knowledge to fix my amp problems from here for quite some time > and I thank you all for that. Well I got one of those Ampeg/MTI V3 combos which is the same pre-amp as the V-7 and just recently the reverb quit working and since the tube and the pan etc. all work fine running in my bandmaster reverb I am going to have to suspect that the circuit to turn the reverb on/off is the problem. The footswitch is also just fine. So before I tear it down I would like to have the pre-amp schematic if possible. At this point I am quuite sure that the reverb is turned on/off with a relay that shunts to ground but if it isn't a relay the schematic would be most helpfull.
thanks for looking and now that I am a member maybe sometime I can also help
