When using these in place of tube rectifiers, since there's no warmup time, I'm If done properly, with appropriate resistors to mimic the vacuum rectifier's voltage drop when running and components that can deal with the full B+ before tubes conduct it works fine Power Supply Design for Vacuum Tube Amplifiers using Rectifier tubes. I was wondering if there was a solid-state replacement for these two tubes (Hytron 6x5 gt/g tube & Super Slivertone 6v6 G), The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes. The silicon rectifier has several big advantages. Radio tubes are valves. Used – Excellent. the lack of 2nd harmonics. They are meant to replace 5U4GB tubes but are sized and built like a metal envelope tube (like a 12SQ7). Old radios are sometimes updated with a solid state vibrator, a simple two-transistor mulitivibrator does the trick, feeding the same transformer. 50. When considering maintenance and reliability, it’s important to note that solid state amps generally require less upkeep due to the absence of delicate vacuum I can relate to the benifits of tubes for amplification but am wondering if I would be better off going with this solid state replacement from a reliability standpoint. I was planning on using a solid-state plug-in replacement for the rectifier tube; mostly because I can’t find the tube.
