Re: 2nd Gen Build
I did a bit of that and noticed it cleaned up well. If I can live with it that way and not have to alter the circuit that would be ideal. If not, the dual masters is a good plan. I never run two cabs anyways. The only bit of the circuit you would need to modify is the bit between the OD2 coupling c...

Re: Hypothetical Amp Discussion
I already have something like this set up on an HX Stomp on my board at the moment, and it does sound great, but we started laughing at the idea of having both loops being tube-driven... And joked that we might as well throw in a tube-driven reverb tank in there too. That's a lot of tubes! 4 preamp...

Re: 2nd Gen Build
Yes try changing the bias point. The gain should rise sharply at some point and then level off.

Re: 2nd Gen Build
What are the voltages at the top and bottom of the drain resistor?

Thanks Dai.
Moderators, maybe this thread should be moved to the new FAQ area?

Re: Robben Ford & His Dumble Overdrive Special
To be fair, the Robben part of the video was a fraction of the overall time. He's talked about his Dumble amps and his introduction to and friendship with HAD many times before, but there always seems to be something new. I agree hearing different players and different guitars was really valuable, a...

Re: 2nd Gen Build
If that is just heater glow you are seeing through the hole in the tube base I wouldn't worry about it. Are you seeing that through the gap between the index pin and the socket? Might the odor be transformer varnish?

Re: The Much Anticipated (?) Bluesmaster Build Thread
I was trying to come up with a rationale, but in the end at 120V the current limit will be the same, Bulb Wattage/120

Re: The Much Anticipated (?) Bluesmaster Build Thread
I usually plug the limiter into the Variac, but I'm not sure that it matters.

Re: The Much Anticipated (?) Bluesmaster Build Thread
A Variac and a bulb limiter is the best arrangement.

Re: My take on a 2nd Gen ODS
The relay spec should be fine. More likely some wiring error, but you say “sometimes” cuts out, which sounds like a faulty switch or relay.

Re: My take on a 2nd Gen ODS
I worked on it some more last night but forgot to write the voltages down. From testing things earlier everything seemed ok, just a tad lower than what is on the layout and schematics since I had my variac running at ~115VAC to get the heaters right at 3.15VAC on both sides. I was thinking verify t...

Re: Robben Ford & His Dumble Overdrive Special
What a great interview! Nice of them to zoom in on the SN stamp ;^), and this has to be the gold standard 102 sound sample.
Thanks for posting!

Re: My take on a 2nd Gen ODS
I was about to say that to keep the 2nd gen's loading on the OD output, delete the 180k to ground and the 1Meg series resistor and go straight into a 250k pot for the added Ratio control. ...Should I pull the 180K and 1Meg resistor as the amp is now or is that for when it has been changed to the hy...
