The Amp Garage

Plenty of great suggestions and safety and circuit protection advice, thank you! I failed to mention that I changed the cord and added a chassis ground, and I agree with the fuse. That is pretty sloppy. I swapped out the ceramic .002mf tone control cap with a .47 just for kicks and I was able to rol...

I've had three O' scopes over the years, Ohio, Heathkit and finally a Tektronix 2225 50 Mhz which I just love. Older CRT scopes are pretty cheap, and in my opinion you get a better feel for what you have your hands on, plus if you are that guy that is always messing around with things, calibrating o...

Greetings experts and enthusiasts, I’ve recently found my self in the possession of a Stromberg-Carlson Signet/22 PA amp. It came out of the local train depot and was absolutely buried in coal dust so I blew it out with compressed air and inspected it for any obvious problems and none were found. Af...

The voltages within this thing are no game. One hand in the pocket whenever it is open and powered up, and the filter caps get drained every time! I got hit by a Super Champ X2 after it had been off and unplugged over 24 hours. Never take a chance.

The parts are on order.

Thanks for the suggestions. The tubes were tested on a TV-7/U tester which may not push them even close to their operating load. The problem with swapping them out is there are six 6L6's that don't come cheap. If I had that kink of change in the ashtray I'd just replace them. I could do a couple at ...

My '78 200 watt Studio Bass has been my sidekick for 30 years but over the last few years it rattles pretty good for a few seconds when I take it off Standby, and then after about five minutes of idle warm up is sounds exactly like dropping the needle between the grooves on an LP with the volume way...

I've got a Princeton Stereo Chorus on the bench and the schematic calls for a dummy plug inserted into input 1 for testing. I have no idea if it should be open to open the plug switch or closed (shorted). Any help would be appreciated.

Thanks!

For what it's worth, I had a cracked solder joint on the bias diode on my '64 Deluxe Reverb that caused all kinds of hum as well as well as other very bad behavior. A bad bias cap can cause hum as well.

Wow! That looks really nice and I really like the size. Is there anything you would do differently? If I am still married after this I might add some tip-back legs. Thanks for posting the picture. Georgeous Tele, by the way.

I appreciate the responses and suggestions. Sorry it has taken so long to acknowledge your time. The existing OT is a Fender branded 125A9A which is designed for a 2 ohm load, so says the internet. I appreciate your suggestions of going with the original configuration of 4x10 but my gigs require tha...

I bought a '64 Super Reverb from a local music shop that has had some serious modifications that turned it into a work horse. The 4 x 10 cab has been replaced with a massive particle board and black vinyl covered enclosure concealing single 15" vintage Jensen speaker. It is absolutely massive and a ...
