I have an old Alpha 76 a two holer that usually perks along nicely at 1400 watts. Imagine my surprise when I lifted the on toggle and nothing happened. An ohm meter check across the 240 volt power pl

Tnx for the comeback Lon and Hal, all that you mentioned ckd ok. I have found a 750 ohm 2 watt carbon resistor that cks shorted, it's in series with the start up relay coil. I expect that when the cu

Contacts in vacuum relays may be cleaned by switching on/off 60/75 watt 120V bulbs. It is suggested to remove all other circuits first, or else. Bob,w5pvr ____________________________________________

About three weeks ago I posted a problem as I could not turn on my Alpha 76. Turns out that the off / on switch is defective only in the "on" position. This is a very early 2 holer S/N 5032, probably

A new Power Switch for my Alpha 76 has been located and is on the way. The filter caps have been replaced. a wrong value resistor is next. Soon I'll have a full head of steam in the old tea kettle. M

6. [Amps] Arcing in C1 and C2 (score: 1)
Author: "Robert Kirkland" <alpha76@triton.net>
Date: Mon, 21 Jul 2008 09:55:58 -0400
Roughly, under load, the rf voltage at c1 should be plate voltage times .9 if this arcs the cap plate spacing is too small or the cap is damaged. If c2 arcs the amp is not loaded properly, ck the ant

I am somewhat worried that 1500 watts from my old Alpha will damage the electronics in my new car. The antenna is about 75 feet from the garage. Anyone heard of this happening ?. Bob, w5pvr _________

The Alpha 76 indicates plate current by converting an 0-1 ma. old 1000 ohm iron vane meter to a volt meter and measuring the voltage drop through a series resistor. The volt meter circuit has an adju

Eric, Forgot to tell you that a defective load cap. padder (lost it's capacity) will cause the trouble you describe. Maybe a near miss lightning discharge did it. Repaired a SB-200 with a bad load ca

Joe, Not familiar with the SB-1000 but if it works on all other freq's then of course the 75/80 Meter circuitry is suspect. The most obvious part would be the C1 padder if the amp uses one. Second is

As a general rule if you can reduce your amp driving power in half you gain a 3db reduction in the transceiver IMD. Less in, less out. Bob,w5pvr _______________________________________________ Amps m

On power up the Alpha 76 meters light up amber, when the time delay is done they turn green, this is normal. When you talk the lights turn from green to amber then back to green this is also normal.
