Thanks for the excellent and concise perspective.

I am looking at building a 100W 4 x 6L6 amp and am wondering about screen resistors. There are some various discourses to be found on the effect of varying values on the screen voltage, but I was wondering if someone has some input or opinion on their effect on tone. One highly regarded designer sug...

Thanks for that!

Nice looking AMP. Can you post the schematics? Or at least, how the reverb is implemented?

We had Ronnie Baker Brooks at eh Kitchener Blues Festival August 8 - he had his Red Plates and did they ever sound great. I had a friend take pics of his setup but don't have them yet. Will post when I get them if there's any interest. Also, Ronnie is a REALLY FINE gentleman to work with and has tal...

Schematic is chock full of problems. I had a gig last night (late reply). Here is the schematic I used and some pics are in the next post. I would imagine this would be high plate with the 220k on CL1, I did not know there was a high plate and low plate version of a bluesmaster. Also the settings w...

The whole GP article talks about a number of Dumbles that Harper uses and where he got them from. But the quote seems to reference a new build. I am also curious about his PAB statement - I understood that PAB was functional whether the OD was engaged or not - or am I missing something?

Quote: GP: Are you using similar gear now that you're on the road as Relentless7, or has it changed since the sessions? Harper:Dumble made me a 100-watt Overdrive Special combo from scratch. It's a new step for me sonically because it offers a preamp boost for both the clean and the overdrive sounds...

You should also confirm that the voltage rating of the insulation exceeds that of the circuit in question.

No. I am not sure who actually makes a 120V rated fuse, I understood most were rated 250V anyway. 2A is 2A.

I plan to anodize and laser etch.

Do you think 1/8" will not be durable? Just wondering as that's what I am planning to use.

Thanks Henry

Just wondering what people use for terminal strips - i.e. adjacent to V1. Could i fabricate those from a piece of glass board and some eyelets? Anyone ever try that?
