Re: Anyone done a PI driver with 6V6's?
I think people familiar with the CF driver schematics and the similar Ampegs might have assumed schematic errors or may just not have looked closely. Perhaps the difference in tube choice between the two configurations make more sense when accounting for the different configurations. (Or did the tub...

Re: Bass Amplification and 2x12" Cabinets - Suggestions
A doubled TL-806 should be similar to the Dr Z "Z-Best" cab. I've seen chatter that if you adjust the port tuning (the shelf length) and put in bass appropriate speakers that it works out well as a bass cab. If the info doesn't come up on search, maybe at TalkBass. (They tend to be a bit down on the...

Re: Coolest Old School Rack Gear
Definitely my MXR M-175 Digital Time Delay. It's a really fun 80's digital delay with built in chorus, flanger and doubler. The deal is it's not a very useful delay, just a run of the mill stale digital delay, but they gave it the ability to self-oscillate well into the audio range. Also it has a w...

Re: Anyone done a PI driver with 6V6's?
Hmm. The expense of a quartet of output tubes for power I didn't need was a factor in my thought. But that description of the 6550 outputs sounds very, very interesting. Maybe a pair of 6550's would simplify things while keeping some of that big amp character.

Anyone done a PI driver with 6V6's?
I keep mulling a low powered 6V6 amp mining the Dumbleland and SSS designs to give a cleanish pedal platform for mostly home use. A lot of the discussion of the high power circuits is about the benefits of the various post-PI driver configurations. I wonder if anyone has messed with drivers in a low...

Re: Dumble Small Special 100 photos (uncensored).
Anyone know of audio samples of a Small Special (or clone)? Or are they so indistinguishable from the clean side of an ODS as to make no difference?

Re: Theatre shooting
All good points but if 20 or 30 folks are armed and start returning fire The attacker isn't going to make it far. The crossfire of 20-30 people all around him trying to shoot the poorly seen assailant in the chaos of a dark, smoke-filled theater couldn't have had a downside? No one would make it fa...

Re: Twin Reverb build
Check out the blackface twins. After CBS took over, the wiring was a MESS. That being said, most of them still sounded nice. I've seen blackface Twin guts and they're better but still don't look quite tidy to me. It's a lot of frigging wire. And I've never seen a BF as tidy as that Mojo wiring pick...

Re: Twin Reverb build
If anyone can show me a Twin with actually fully tidy wiring, I'd be impressed but looking for snubbers and listening for squeals. It's almost too much wire to have any hope of tidiness.

Re: What can I do to an early 70's bandmaster?
This has always been the deal breaker for me with Bandmasters, and Pros. The smaller OT seems to work out better in Vibroluxes, but the Bassman and Twin OTs rule for my money. It's curious, that. Lots of people love Vibroluxes. Something about how the pair of tens delivers with the smaller transfor...

Re: Dumble SSS - history and info
Other than #5 having Peavey iron, do we have anything solid info on what model iron in that case or what other iron the 150 watters used? Do we know what was used in 150w Dumblelands?

Re: Gibson Historic potentiometer....
Hah! I've been looking to see if anyone does the true log stuff with pull switches or dual concentric for some wiring projects and not coming up with any luck for anything that looked of the same breed as the Historic pots. I'm gonna just try my luck now.

Re: What distinguishes a SSS from a Dumbleland?
From this I would deduct that the 2 Reverb CF/mixer tubes would be omitted in those amps along with alot of their feedback networks too? Interesting given those touting the CF/mixer tubes being a part of the SSS "magic". Or maybey HAD found a way to include a CF mixer with only 2 reverb tubes to pl...

Re: Fender Vibrato Circuit: Twin or Princeton?
Hmm. Might have to think more about VC preamp bias based options. No issues with post-PI driver stages, ala SSS. Harder chop is good with me, too.

Chassis drilling templates?
Over in the TW file section, there are templates placing all the chassis holes on the standard sized chassis that Ken Fischer used. Is there anything like that for any Dumbles? (HAD interviews have him indicating that component layout on the chassis is important enough that you wouldn't get the same...
