||Ampeg flip top electrolytics|
Anyone know of a source for suitable electrolytics for the Ampeg Portaflex amps?They have the multisection tubular electrolytics in 40X40X450 and 20X20X450.
CED has some but they are only 160VDC and not the correct value.

http://eurotubes.com/ has a decent selection of JJ can caps, including 50x50x500 and 32x32x500, which should be OK as substitutes. You can call or email Bob to check the sizes...

Thanks guys but tubes and more is CED and they don't have the correct ones but the right type.The JJ cans are the wrong type.
The Ampeg Fliptops have the long tubular type caps like the old gibsons had .Two hot wires from one end and the ground from the other.I'd double up standard electrolytics but it's cramped for space and then I'd have to fabricate some kind of bracket to mount them.

I use the F&T axial caps for those. They are small enough to fit side by side in that space. Get some plastic ty-wraps with the screw holes on the ends to fasten them in place using the original screw holes. I also wrap the caps under the tube sockets with fish paper or insulating cambric to prevent accidental punctures. When the amp is upright the caps will lean towards bottom anyway. I have done this quite a few times with no reported problems.

Thanks John.I have some of the F & T's in stock and imagine that's what I'll end up doing.

Remember they are just filter caps, so you can mount them anywhere. They don't need to be where the old ones were. Leo Fender stuck all of his in a box on the outside of the chassis for years. Since modern axial lead caps are so much smaller than they were in the old days, they can often be mounted on the parts boards, but nothing says you can't mount a couple terminal strips somewhere at the end of the chassis for new caps, and run wires back to the circuits.
