Hey sneakers563!

I’m only six years late to the party…. . This is really cool! Is it still available in the iOS App Store? If so, what is it called? I tried searching for Tonestack Calculator, but I didn’t see any relevant results.

Thanks!

Hi Franco,

I'm here!

I'll send you a PM.

xtian, Thank you for the heads up....

Thank you, Martin. The reason I thought CDE were no longer making caps is that Mouser only have about three values of the 6PS caps in their database. But it looks like CE Distribution carry the entire line. I have a vague recollection from maybe 10 years ago of reading something to the affect of the...

Hi Guys and Gals, Resurrecting an old thread here. These days, CE Distribution has polyester orange drop caps listed for sale. CE says the brand is Orange Drop, but the data sheet they link to is clearly Cornell Dubilier. Are these caps to be trusted? Anyone using these caps from CE care to opine? M...

Larry is one of my favorite players for the last forth-odd years. Tasteful harmony and laid-back phrasing. Oh and “tone for days” doesn’t hurt either.

In my 40-some years of working in electronics, I have made a number of attempts to learn code. Every time was a complete failure. My brain just isn't wired that way. It makes my head fell like an explosion is eminent....

I have always enjoyed this forum. A little civility goes a long way; especially these days when the entire world seems to be melting down. People are doing things these days that are more despicable and/or stupid than ever before.

Tape off that CT and stick a bridge rectifier in there. WOWZERS!!!!! Now you've got 1,087 VDC!!!! What can you do with THAT!?!?

Nice work! I'm going to grab a handful to try out. Couple of questions: What is the weight of the copper laminate on your PCBs? Also,... are you committed to the dark mustard color? (Not saying there's anything wrong with that.) But I'd pay a little extra for a black solder mask (or red, or blue). ...

Let that be a lesson to ya, sonny! We’re here to build TUBE amps, from input to output! 🤣 I wish I had some advice for you, though. It does seem weird that the 24V supply fuse is good, but the power supply itself seems to have died. Let us know what happened when you get it sorted out, please. Ciao,...

That would be my guess, but that’s only based on what I’ve read here. You might also look to some of the Hiwatt designs as well. Again, no personal experience with them. But I’ve read they are very clean.

It's not an RMS meter, but given the readings I got I'd say it was close enough. All you need to do is get the peak to peak voltage on your scope, then divide by 2.828. That gives you the RMS voltage. Ciao, Lou Isn’t that only valid for a sine wave; and the waveform on a screen grid may be way off ...
