Easy enough to sub a 5Y3 with a pair of diodes and a resistor that simulates the plate impedance. The damaged valve was a 5U4G. That's not going to be easy. You can find Fetrons and even generic MOSFET devices that can replace a triode as a generic amplifier but as is they won't emulate the characteristics of a 12AX7. For instance, the AMT 12AX7WS Warm Stone is a solid-state replacement for traditional 12AX7 The example shown here, a TR1002 solid state diode produced by Teledyne, is a 7 pin device intended to be a drop in replacement for a 6AL5 electron tube. Apr 12, 2020 · A lot of places are now developing Solid State 'Tubes', although with no need for a vacuum inside. g. Due to the fact that instead of the expensive Oct 12, 2020 · The first real commercial solid-state replacement for a tube triode was the Fetron. If this is done with no load on those tube's filament supply, the test readings will be inaccurate. However, most of them go on and on about how they sound “just like tubes. The YJR converts your amp's vacuum tube rectifier to a solid state rectifier, reducing tube sag for a tighter sound and feel. You can easily make one but Bill supplies the adapter, loctal socket and tube for this price. I used a 10W resistor to compensate the heat from the resistor. The original type 83 tube was filled with mercury to regulate a voltage drop of about 15V when new. $30. Finally, there are the solid-state replacement options which are roughly comparable to the cost of a Oct 16, 2019 · I am referring to these „SS tubes“: 5 Pcs NOS National SSR-8 solid state replacement for 6X4WA / EZ90 Vacuum Tubes | eBay Arne Last edited: Oct 16, 2019 The type 83 Solid State Tube replacement module is designed for Hickok and B&K testers that have a need for type 83 tubes. Dec 15, 2015 · Solid State Fullwave Rectifier Tube Replacements An alternative to using a vacuum tube replacement is to use a solid state tube replacement. I was thinking of using one of the SE5U4GBs to replace the 6X5 by rewiring the rectifier socket to the appropriate pin out, but I have a couple of questions Jan 22, 2021 · Here again, many famous and popular amps were designed to use a good solid state rectifier: Fender Twin Reverb, Carr Rambler, etc. Many years of development have resulted in this device, featuring extreme stability, automatic matching, no adjustment required, “tube” like sonics (2nd order products) with an automatic 30-50% power This octal based solid state rectifier is a cost effective replacement for any of the following tubes: 5AR4 / GZ34, 5Y3, 5U4G / 5U4GB, 5R4 / 5V4 / 5Z4 Not only is this an inexpensive alternative, but this solid state rectifier will firm up your low end.
