With a 1 amp fuse in the amp, maybe the transformer is not gone. Unhook the secondaries and see if you still have voltage.

Thank you Don, you're a scholar and a gentleman. I removed all connections(no jacks hooked up and no connection between the master volume and the PI cap) between the PI and the pre-amp and was still getting sound. After reading your post, I grounded the PI input cap and no sound came from the guitar...

I should have been more clear. When I say "signal", I'm talking about a guitar being played into the input of the amp.

The amp is a 101 non-HRM. I recently added pre-amp out and power amp in jacks. The jacks not connected via a switch. You have to use a jumper to connect the jacks and make a circuit between them. Without the jumper there should be no feed the the phase inverter. When I remove the jumper I still have...

Merry Christmas to everyone!!

Thanks again glasman, much appreciated.

Thanks glasman. So any tank that will work with a Fender will work here? Also, some units have 2 springs while others have 4 springs, what difference does it make?

Thanks

Thanks for posting the schematic and layout. I'm a noob when it comes to reverb, does it require a particular reverb tank or will any on them work? Also, what output transformer did you use?

Thanks,
Ken

I believe the one I'm using is a 1/8" which is going to put some of the eyelets very close together, if not slightly touching. There is a smaller 3/32" that you may like better for more room.

I know a lot of guys are using PCB's, but if you are a do it yourself type or don't happen to have a PCB, this may be of some help. I just drill out the holes on garolite, install the eyes and solder in the socket and wires from eye to eye where needed. The DIP socket is a 16 pin, and there are only...

Brain freeze . My eyes were seeing mw and my brain was thinking ma.

According to the specs you posted, the relay is pulling 200 mw at the coil. Is your transformer large enough to handle the load? By comparison, the NTE pulls 15 mw.

Where do you get that stuff? My coax melts like butter whenever you get the iron near the conductor..

One source is Steve Slater at Apex Jr. Good prices too.

dobbhill and Gil, thanks a lot. That gives me a bunch more options to look at.
