1. Re: [Amps] L-7 (score: 1)

My needs are opposite. I would like an L-7 without the power supply (have a very stout 4000 v supply) but having the power supply would be ok. Any good amp covering 160 to 10 m, using a pair of 3-500

I have a homemade 8877 amplifier that covers 160, 80, 40, and 20 m and used almost exclusively on cw. The power supply puts out a very stout 4000 vdc. The grid overcurrent protection circuit is set t

Years ago when the cycle per second (cps), a descriptive term, was named a Hertz, a non descriptive term although in honor of a great man, why was not the liter per second named a Falstaff? 73 Paul W

Some years ago there was posted a suggestion to help protect the output tank circuit of the SB-1000 from parasitic resonances. As I recall, it involved a small silver mica capacitor and the 40 m tap

bad thing? It may be a North West English expression, but-- Back in the 1920's and the 1930's a very common expression was, "That's a cracker jack", meaning something of outstanding quality. 73 Paul

Richard I have been using a three phase transformer on single phase for several years. Two of the primaries are in parallel (240 vac), their secondaries are in series--the third bank is left floating

Jim Looked in my junk box. Have a small tuning knob for the ARC-5 transmitter--but don't think that it will fit the receiver. Also, I still have a tuning capacitor for the 3-6 mcs ARC-5 receiver, com

I have a Command Technologies HF-1250 amplifier (single 3CX800A7 tube). The amplifier does not have grid over current trip out protection. On all bands except 160 m It is working fine (700 to 800 wat

Thanks for the replies. I, too, at first thought it would involve a padder in the output tank circuit. Something I should have out in my first post: there are no padders in the output circuit. The sc

My thanks to all who have responded. Yesterday I hooked the amp up to a dummy load. If I tune quickly, the tuning on 160 m behaves normally, even at moderate power-600 watts out. If I hold the key do

I really didn't know what was the cause of the grid current changing, creeping or rising rapidly, depending on loading, only on 160 m, but it did seem that something was heating up and changing with

This amp, which has factory installed QSK, works fine sometimes, but other times it doesn't. I do not use QSK; I switch between transmit and receive manually. When transmitting on CW, the output powe

Everyone is free to use whatever nomenclature he or she wants, but communication is easier when everybody uses the same nomenclature. Currents exist in places other than wires or inside vacuum tubes.
