Schematic..... 6K6 like the standalone reverb?

[Bob-I]

I'm in the process of building a Fender style standalone reverb for a friend and it got me thinking. Why don't we use an octal tube like a 6K6 or 6V6 for internal reverb drivers? I'm not tube savy enough to do all the calculations, but I'd think that it would be far warmer then the 12AT7 driver.

My thought is to simply replace the parallel 12AT7 with a 6V6 driver. Before I do something that requires punching out a larger hole, I thought I'd run it by the good folks here in case I'm missing something.

Thoughts?

If I'm not mistaken, some current model Fender amps (the point to point ones) have this type of reverb. Essentially the stand alone reverb circuit built into the front of the amp. Not sure if they use a 6K6 or maybe 6V6.

If I remember correctly the Tone King Meteor II uses a 6V6 for the reverb.

I made one a couple months ago. It works really well in the passive loop. It isn't as good in front of an amp. When I get to it, I'll mod in a switch to convert it to a 6G15. It is pretty close to that now except for taking the signal off the plate instead of the cathode.

I think I took a picture of the guts. When I get home I'll dig it out and post it.

Traynor used the EL-84, which when hooked up as a triode works really well. Same socket size too. They used it in both transformer and cap coupled (Ampeg) styles too.

I just did a cap job/restoration/maintenance on a traynor YGL3A MKIII with the EL84 Reverb driver, man what a sweet chimey sounding amp! I just don't get it, I mean the Traynors had great components, MUSTARD CAPS, Mullard tubes (In alot of cases) and go for less than MV silverface fenders on the used market. some of them had goofy circuits, but this one was a Twin reverb(almost exactly!) with EL34's and nicer reverb.

And the front. I used a 3 spring, medium decay tank. sh

I just looked up the schematic, very cool amp, and exactly what I was getting at with the reverb driver. Since the EL-84 uses a 9 pin I think I'll give this one a try.

Yes, yes... That was the amp I gigged with through much of the '70s. Sweet, indeed - maybe a lil' heavy in an Anvil roadcase but my back was much younger then.

[Funkalicousgroove]

Yeah, it was a BEAR to move around, but those trannies are DEFINITELY over engineered. If I needed a giggable amp for a couple hundred bucks this would be high on my list for sure!

If you are thinking about getting off the Fender reservation, I would have a hard look at the Ampeg set-up. I have always loved the verbs in the Ampegs, especially the Gemini's and Reverbrockets. It seems it is part of the sound rather than added to it. I did a ground-up restoration on a Gemini I last year and the reverb is great.

You can still get the higher impedance tanks and 6CG7 tubes pretty easily. IMHO, this is a better reverb for the "D" amps than the twangier transformer-driven tank. Plus, you save a little real estate not needing a fifth trannie.

I had a Traynor MKIII with the EL84 reverb and I've played the Fender Zinky amps with both the EL84 and 6V6 reverb drivers. I prefer the Octal tube driven circuits; I think they have a smoother tone to them. The El84 sounds harsh to me.

I built a Revibe with a 6K6 which I use in the Dumbleator Loop. The 6K6 seems to have the sweetest reverb tone but it does need lower B+; the 6v6 is a good 2nd choice...

With guys like you broadcasting it on the web, that will change in about a week...lol. They are truly sleepers. Some of the first ODS mods were done on YBA-1's and Bassmans. The Traynors always shined, and the 2 X EL-34 ODS mods screamed seriously good. Lots of clean headroom too. The ones with 2 x 6550's running like 580 volts are downright righteous.

My first casualty was a YBA-1 that became a McIntyre Bluesmaker. I got it in trade for a fret job. The real sleeper in the group is the Voice Master. It is a four channel, 50watt, tube driven mixer/PA. It has the same power amp as the other two-tube Traynors and it has eight pots on the front panel which makes it a very good candidate for a "D". Acres of room on the inside too.
