Re: Maybe someone can help me with this color for a guitar.
I'm not an expert, but that won't stop me. To me, that looks like a flamed maple top with a burst finish. The black stuff has to go over the burst. So, start with an ordinary burst. Paint it all yellow and blend in the brown-burst around the edge. The black stuff? I dunno. Cut a stencil? If the top ...

Re: Gibson GA-50 tone stack
You still have the bass pot grounded. That's a mistake. The bottom lug goes to the 2.2K and then the PI. That's not what my schematics show. That 2.2K is the PI cathode resistor and it connects to ground. Same for the ga50 and ga50T. Has nothing to do with the bass pot. Gibson is well known for mul...

Re: Gibson GA-50 tone stack
I was unaware and asserted a view not supported by experience or evidence. I should not have said to skip the mic channel. Sorry and thanks for mentioning.

Re: Gibson GA-50 tone stack
Thank you for the kind words...I generally figure no one is paying attention to what I do. I'm not so sure about using a 6N7 in place of a 6SN7. The 6N7 has a higher plate resistance and twice the gain. I don't believe this is a good thing for a paraphase inverter. My primitive understanding and lim...

Re: Gibson GA-50 tone stack
This is from a GA-50T not GA-50. There is a big difference. Be certain of which amp. Lower pot is not grounded. Some things are not placed correctly. The 500K instrument pot gets input to wiper from J2-J4. The long wire going down doesn't belong there. Maybe this helps?

Re: What should I build?!?
It is impossible to know a person's wants and likes without more information. Also, your post demonstrates how differently one individual's idea can be different from another's. You say 50W or less, not too loud. I think 50W is really loud. So, where does that leave us in terms of helping you? I sug...

Re: Broken 5E3 for sale locally - worth checking out?
That price is ridiculous. You can buy a quality kit new for that price. Of course, that's no speaker and no cabinet. Still, buying someone else's problems for that price? You should pass or offer $250.

Re: Yet Another Two Stroke build
Ah, thank you. So when they say 7000K primary/4,8 ohm secondary, that's not actually correct, as it's 7000K to 8ohms, and 3500K to 4ohms.... That explains some of the things in Dave's book that weren't clear, like why you might want to plug an 8ohm speaker into the 4ohm secondary when you run a 6V6...

Re: Need help tweeking a schematic for 6k6 amp
You didn't say what you'd like to see for plate voltage on the 6K6's. Instead of the 325-0-325 PT, I might go down to 275-0-275. I didn't do any calculations, so this is a SWAG. There isn't that much difference between 6V6 and 6K6. Aside from the choice of PT, I'd probably build it as shown.

Max,
Even if that were so, you are probably invisible. I know I am.

Re: PSA Hammond transformer blowout
I'm reasonably sure most of us have a story like that. My rule of thumb on eBay is don't spend more than you are willing to lose. I keep my expectations low. I'm generally well rewarded. I had one incident where "my package" was delivered (supposedly) in San Francisco. I live in Baltimore. Details n...

Re: Speaker Cabinet Handle Screws
T-nuts have their place. In general, I'm not particularly fond of using them. In harder woods, I find the spikes bend over too easily rather than driving into the wood. They are fine for pine and plywood. I've grown to prefer threaded inserts over T-nuts. In any case, without a compelling reason or ...

Re: Speaker Cabinet Handle Screws
What is the objection to a through hole so you can use a washer and nut on the inside? That will be sure to hold the weight. If the screws are too long, they can be sawed off. This is simplest, least expensive, and sure to work as desired.
