Happened again!!



Unrelated to the stereo, light switch fixed it.

This may be totally, or at least moderately off topic but....

Is it crazy for me to try to de-magnetize a speaker in order to make it less efficient? (the whole cranked amp, low volume thing...)

Yep! Just as long as the tubes' plates aren't glowing red.

Yep. Not all original Fender speakers are really that great, a little counter-intuitive, but new speakers can help out a lot of old Fenders a great deal (at least from the mid-sixties onwards) if they are a good match for the amp. Power tubes can wear out, but if the originals are still testing good...

One advantage of recording myself is that there won't be anything else going on in the room, though. What, no Gould-ian grunting? http://video.google.com/videoplay?docid=-6984208089899995423 Sorry.

Also check out www.Angela.com's How-To Section, some really great, simple projects in there with parts lists and advice. Of course you'll have to do some metal fab., but that's part of the fun.

The only thing is it only has one firewire port, so you would need to use that for an HD and have a USB audio interface, may not be a problem for oyu, but worth thinking about. ....I run a dual 1.25g G4 with 1.5gb ram and DP4, I can bog it down if I really, really try (20 or 30 tracks at 15 minutes ...

I guess this topic is getting a little theoretical at this point, but anyone's help regarding power-supply design is really helpful. Thanks! I'd suggest googling Williamson and Mullard amplifiers, Dynaco, Eico, Heathkit designs, etc., there are a ton of them up online that will give you a really go...

Since the target is a hi-fi amp, i think sag would be largely undesirable. In theory, I could mayb use Zeners for each voltage stage of the power supply and end up with something pretty solid? Not necessary in my opinion.... The plates of the power tubes draw a lot of current, much more so when "as...

Even if I use a SS rectifier and a fixed bias supply, can't I just bring voltage down to whatever I need with a resistor? Isn't that how most tube amp power supplies work: to first supply the highest voltages to the power tube plates and grid, then progressively step it down with resistors for the ...

Ha! I was just working on a pair of 57's an hour ago. I think they may be Chinese counterfeits, but the yellow lead went to the terminal with the red marking on it.

I've bought records like that, I happen to think that it is the awesomest thing ever.

890 volts will yield about 560 volts rectified, which may be ok for a 6L6 but is really high for a 6V6. There are some tricks to compensate though - what kind of rectifier was the amp running? An old coke bottle 5U4 will drop your plate voltage by 60 volts or so (but of course introduce sag) and cat...
