2/11/2024 0 Comments Guitar amp tube socket smoking![]() The 6L6GC tubes were working before the mods, I also replaced them for a fesh pair of new working 6L6 GC and there's still no cathode current reading or output sound. The device works properly as Im able to use it perfectly with other amps, also used it with this amp before. I'm using this device to measure the Cathode Current: Tubes Light up and the plate voltage is 497V. In small 9 pin tubes, you usually see a combination of tube socket and shield or retainer. It’s worth noting here that the perceived volume of tube amps and solid state/digital amps is not the same - that is, usually, a 20W tube amp will be louder than a 20W solid state amp. Also the theres no output sound going to the speaker. The amplifier was working before this mods,īut now although I have negative bias voltage I cant measure any Cathode current on the 6L6 tubes, it reads zero current. WARNING: A tube amplifier chassis contains lethal high voltage even when unplugged-sometimes over 700 volts AC and 500 volts DC.If you have not been trained to work with high voltage then have an amp technician service your amp. Based on the research we did, we think Electro. Sold comparable range in price from a low of 20.95 to a high of 2745.00. We have done a lot of research to find the top 20 Western Electric Guitar Tubes available. The stock schematic of the amplifier is here: Choosing the Western Electric Guitar Tubes can be difficult as there are so many considerations. ![]() I've narrowed it down to that socket as I can hear it if I knock on the tube. It's not the tube because I've cycled a few different tubes through that socket all with the same effect. I schematic of the Bias supply circuit with these mods is attached, new resistor values in RED. I have a Fender Super-Sonic 22 Combo and it has one socket that has a ringing very similar to a Microphonic tube. Act Today to Secure Tomorrow Our cherished hub for guitar amp enthusiasts. I used an CTS 10K bias Pot, and adjusted the resistor values on the circuit so that I got a voltage range with the Bias pot from -44V to -58VDC tube flashing light followed by the amp dying and smoke) You would. I'm modifying my tube guitar amplifier with an adjustable Bias Pot instead of having fixed resistor values.
