Report Review for product Solid State Rectifier - Yellow Jacket® YJR, For 5AR4, 5U4, 5Y3

Works great. Easy drop in replacement. Installed it in my 59 Bassman Ltd. Greatly improves the attack of the amp. I wasn’t big on the tube sag. Increases the amp output as well. I feel it made the amp more responsive and I installed this as part of a full re-tube and re-bias. Increases the plate voltage by about 10 volts. Seems like a well made unit.
