Crusher, I did the same thing with my GS35B amp, my B- was 50 ohms above ground, that was too much. I dropped the 50 ohms down to 1 ohm. This is what it looks like on paper however, where the diagram shows Zener #1 and Zener #2, I have installed separate Triode control boards which allows me...

Yup! .

Greg, would you please elaborate on the statement that I highlighted in bold; numbers and names, maybe even a List of the "Top Ten" builders of amplifers powered by alternating current. What makes a builder good or bad, what are the criteria that he or she is rated on? A...

I made my own interface to use with my 706MIIG, the first was with the data jack but I did not have any luck with it; the signal out is influenced by a squelch signal. I used a RJ-45 plug to make my second one and connected it into the aux. mic plug. It is controlled by the volume control...

A bifilar choke is two pieces of insulated wire wrapped on a ferrite core, the purpose is to block RF from getting into your house AC lines. For your application, if you could fine a ferrite rod (like the kind you find in old AM broadcast radio sets) about 2 inches long and wrap the wire...

Excellent idea, be sure to wind some bifilar type chokes (one for each bank of 5 tubes) and place them in your 120 volt series filament supply line; this will keep RF out of your AC wiring at home. .

TRUE STORY: I went to my to my doctor's office and during the exam, I said, "Doctor when I do this (raise my right arm over and behind my head), it hurts". My doctor looks at me and says, "Well don't do that"! We had a great laugh over it! If, your amplifier works as it normally should...

My first amp was a Hooker-100, I bought it brand new in 1975....... What kinda power transistors does it have in it, can you post some pictures of it? .

Here's Your Stage! .

I am Black but, I am neither the Pot nor the Kettle; I don't build or sell transistor amplifiers........."Mopower2ya" .

I have to agree with you for the most part but, I did not "attack" anyone personally or individually but, I did attack the IDEA that the actions would be repeated; my "assault" was on the sensibilities. I went "South" here, my message was supposed to be directed to "The powers that be". My...

Ditto to what the man said. GI = GO, Garbage In equals Garbage Out. .

Observation: "Great minds discuss ideas, mediocre minds converse about events, small minds talk about people". First, I don't own anything here, moderate any sections or, set any policies around here but, I would address my statement and questions to those who do. For 18 months, a thread...

B+ Supply transformer is 2500 VAC @450 ma CCS .

Set the Driver Plate Tuner at half mesh, on the final stage, fully close the LOAD tuner and set the Final Plate tuner at half mesh. QUICKLY, key it and tune the driver for a peak on your watt-meter (key for no longer than 3-5 seconds until you have max). QUICKLY, key and tune the Final...

Nope, I tried that and more; problem is, the 8908 is a Pentode tude, the suppressor grid is isolated as is the screen, the Control Grid and, the cathode. In the 6LW6, the suppressor grid is internally connected to the cathode. The 6LW6 is not a direct substition for the 8908, the 6lw6 has...

8908's Where are the tubes for that thing? .
