Shared screen resistor question

[cbass]

Aha. I based what I said on lots of assumptions. You know what they say. If you assume you make an ass out out cbass.

Edit:

Looks like two of the tubes are being sacrificed on the altar of tone. Nothing between the screens and AC ground. I wonder if a screen short would turn the 390R into a fuse before it turned the fuse into a fuse.

[Reeltarded]

Both, it appears. Not fused with a slo fuse either f3A

This is why I don't like 84s even a bit. The tubes are fragile and the amps they build around them are built like cardboard cowboys.

Ping. Ping. Pow.

Bad filter cap could cause that resistor to blow too.

These things are known to have bad filter caps. It may have been a bad run of caps but 3 out 5 I've looked at needed some caps changed out. Check them.

Also use 2.2k screen resistors with el84s...the tubes will run with less trouble.
