    I’d appreciate if anyone has a 5R4GY Rectifier Tube by Phillips or RCA they would be interested in selling.

    Hi Ken
    That seems to be a tricky one to find but the prices from some suppliers isn’t that bad compared to some wanting the world. What is the application other than a guitar amp? I have 5U4’s crawling out of the woodwork in my hoard but other than that they are usable depending on how heavy your transformer is as the 5U4 has a draw of 3 amps compared to 1.9 on the 5R4 and some mention the 5U4 will end up with a small voltage drop as well. I think the 5U4 was very common in the old B&W TVs if memory serves correct.

    Hi Dave. I have a bunch of them. I would have to put them on the tester to see where they sit.
    Interested? $20 each. Pickup in Calgary
