electric baseboard heater+volume...

[nyazzip]

just a mildly amusing observation...whenever my electric baseboard heater cycles on(which is often, in the past few weeks) the volume level on my mono rh-84 drops precipitously. took me a little bit to figure that one out....also a tube FM receiver on the same circuit; not sure which one it is suffering from the voltage drop, the amp or the tuner. i'm kinda suspecting the tuner

Probably both.

Anything but a triode will be more than moderately affected, because a pentode, even wired triode, sees a drop on its screen and transconductance tanks.

Cheers!

Best to have electric baseboard heaters on a separate circuit from other loads. Is the baseboard 240-V or 120-V? Resistance heaters are better on 240-V circuits, so current draw and voltage drop are lower.

its a 120v circuit. probably 20 amp. i'm not worried about it, i just found it amusing. modern conduit wiring/breaker. i have dropped the line voltage down to 50-60v on SE guitar amps before without this much volume drop, so i am suspecting it is the vintage FM tuner that cannot cope, rather than the amp. i could easily confirm it, if i wanted to play around with a bunch of connectors....
