    Looking for someone to work on my 2x4-1000 amps

    Let's just say that, "I been there". Too many 450 volt electrolytics strung together trying to reach 5000 volts, that accounted for the snaps and for-what-ever-reason it would occasionally arc during tuning. Sounded like a .45 ACP at close range. Now-a-days, the owner would have to take...

    lafayette HA-270

    Hey Kid, You have a 200 watt pep 2 tube amplifier that has a transistor switching power supply to make the 700-900 volts that the tubes need to operate. The sound that you hear is the transistors oscillating and it is normal. It was made for four watts drive input. Expect to see about 100+...

    Looking for someone to work on my 2x4-1000 amps

    When I first replied to this thread, I did not realize that it was almost a year old. The thing about 4-1000 amplifiers is that they are BIG, the tube needs 4000+ volts on the plate and the filament requirements are great. I worked on a couple a few years back and the thing that strikes me...

    How's the amp running now? Four volts low is better than 12 volts too high. I think the drivers may have been toasted by the excess volts. .

    1.0 mh Choke

    Speaking specifically about the plate choke if, you are building a single band amp especially for thr higher frequencies then resonance is not an issue, the more turns the better. Same deal on the bi-filar / tri-filar input chokes on directly heated Cathode tubes. My way for GS-35b input...

    Looking for small cb amp

    Maybe you might be right but, you might also be wrong. Did you yourself perform the modifications on your radio or did some "Tek" down at the local Pilot Truckstop do it for you? I only ask because I know what's been done by me to the inside of my radio and, my radio SPEAKS for itself. I am...

    Galaxy 1000 final tubes ID

    Those tubes were made with a rare earth Phosper called "unobtainable-um", it was all mined out in the 70's so, the only place they MIGHT be is in the corner of some warehouse in some third-world country somewhere. .

    1.0 mh Choke

    I like the way yours looks, well thought out and everything is neatly mounted. What solution did you come up with for the tube sockets, did you make your own or did you buy "production" models? What about your filaments and bias circuit; when I first started, I paralleled both tubes on the...

    What Is This Animal ???

    To the left of the transformer on the deck, there is a choke; this is the B+ (Plate choke). There is a wire running west from the choke to some point and then it goes vertical to supply B+ to the tubes (Where the parasitic suppressors are all tied together). The Tank Coil is between the two...

    How many "Valves" does it have, what are the numbers on the tubes and what is the configuration? Pics would help also! .

    Right, that is pin 3 (not pin 5) so it should have plus volts on it. Read the voltage on pin 5 to see if you have any bias volts on your tubes, it will be in the 15 to 20 volt negative range (put your plus probe on ground and your black probe on pin 5). .
