Re: Why no B+ fuse?

A lot of older tube amps just had a mains fuse, Fenders being one of the most conspicuous. Marshall has usually had a B+ fuse, except in the 18watt and other smaller amps. Heater and Center tap fuses are common on Peavey amps, but not on most others. I almost always add a B+ - it is good insurance a...

Re: Need Help - Gibson Amp Tremolo

Richie, I was a little worried about it not lasting, but since the lamps isn't brightly lit, I think I'm Ok. Since it's a grounding tremolo, if it stops working it the rest of the amp will work fine without it. Then I'm sure I'll see it back.

Re: Need Help - Gibson Amp Tremolo

I just wanted to report back that I found a solution. I took a chance and bought several 12 volt lamps and the 5 pack of photo resistors. I hooked the lamps up to see which worked best and picked that one. It is RS part #272-1141. I picked the medium sized photocell. I used heat shrink like the Fend...

Re: Need Help - Gibson Amp Tremolo

Thanks for the response. Yes I'm sure the LDR is bad, a wire is completely out of the unit. I'm trying to not re-engineer the tremolo circuit too much. I have tried the Fender and it appears the off resistance of the photo-resistor isn't very large. As for the Ampeg replacement unit - I have used th...

Need Help - Gibson Amp Tremolo

I'm fixing a Gibson GA77RVT. I've got it working except for the tremolo. The LDR assembly is bad and I need a replacement.

Any ideas?

Can I get a Fender LDR to work? If so how. I've tried it, but still no joy.

Any help is appreciated.

Re: The End of 18Watt.com

ZPhil has posted some criptic messages at Trinity and ax84 saying all hope for 18watt is not lost. He's in contact with Graydon and says there's some hope that 18watt will be back if Graydon can figure something out. I'd suggest you send a short note to Graydon at GDSAmps and let him know how much y...
