On the old Ampage forum there's a thread about curing Fender amps "farting". Bruce Collins posted some great suggestions along similar lines to...

[JoeM]

Leo, I'm very interested in your method of connecting both channels for reverb and trem. Would you mind sharing?

[JoeM]

Anyone have a schematic for the Fender 68 Custom Deluxe Reverb?

Thanks!

[JoeM]

It's known that HAD tweaks his amps for the particular player,so no one really knows the exact circuit. Accordingly, I don't give too much weight to your...

[JoeM]

No, that amp is not modified by Dumble. My point is a player of Larry Carlton's caliber can play through anything and sound great. Most recent concert a friend...

Larry Carlton with his ... Twin Reverbs...

Maybe Gerald got the idea from Pittman, only my Weber book has the trainwreck pages.

I had a chance to speak with Aspen Pittman at one of the...

[JoeM]

Leo, the Trainwreck Pages are in a book by Gerald Weber, Pittmans book IIRC, had quite a few schematics.

[JoeM]

I don't know about marketing. It seemed more like "Lets see what I can do with this" Better balance was the possible goal, but that would be more...

Some of you may have seen an article in Glass Audio about using a CCS instead of the tail resistor. (LM334 I think).

[JoeM]

Alan, isn't the 25130 the PT for a Deluxe Reverb? There's quite a few people that use 6L6s in the DR.

Yes,Heyboer makes very good iron, so does Hammond.

[JoeM]

Mate!

[JoeM]

Get away from vacuum tube circuits.

[JoeM]

Yes, that's the way I've seen done frequently too, with a big rheostat in the cathode circuit. The Fisher circuit doesn't require a high current pot.

[JoeM]

No it's not a rheostat. Some of the voltage off the divider adjusts at the tube grids (i.e. via the pot wiper), placing more or less + voltage to adjust the...

[JoeM]

I'll have to find the link or info, but theres a very cool way some old fisher amps had a variable cathode bias method....

[JoeM]

Go to the old board and search Fisher bias.

[JoeM]

We're not discussing CC vs MF, but CF vs MF. Not a change worth the effort, unless you need the lower noise of MF, maybe in a high gain amp.
