W3SLK asks for a capacitor (I've got one) but his e-mail server won't accept an e-mail from me! Mike, contact me, and put me on your "acceptable" e-mail list.

I repaired an LK-550 (three 3-500z's) that sounded like a .22 caliber going off. It was the fuses. I removed all 3 tubes, and put them; /archives//html/Amps/2004-12/msg00100.html (9,296 bytes)

I had an Icom 738, and a homebrew 4CX1600B amplifier. The needs of the relay in the amplifier were well within the specifications of the Icom transceiver.

No, it's not an IC, it's a small rela; /archives//html/Amps/2005-02/msg00103.html (9,132 bytes)

The hose clamp could result in some pretty big stresses in the tube. Rich Measure; /archives//html/Amps/2005-02/msg00153.html (7,260 bytes)

31. Re: [Amps] Quick 220 outlet? (score: 1): Author: gdaught6@stanford.edu; Date: Wed, 09 Feb 2005 10:44:41 -0800; Well, it takes voltage to make current, right? I always think of the human body as a 10kOhm 2W resistor. But if the current is directed arm-to-arm across the chest (i.e. through the heart) even a sma; /archives//html/Amps/2005-02/msg00343.html (8,385 bytes)

If you've ever tried to start an engine that's at about zero degrees, you'd appreciate such a "block warmer."

34. Re: [Amps] AL80B Tube? (score: 1): Author: gdaught6@stanford.edu; Date: Fri, 04 Mar 2005 14:54:50 -0800; I agree. But the problem MIGHT not be in the tube. I once encountered an amp with exactly these symptoms, but even trying a couple of good tubes didn't help.
