Re: HH cabinet bottom panel voltages

Hi Mark,

Thanks for the quick and helpful reply :-)

Things are probably OK. When you measure unregulated DC voltages
with a DMM, there will be a great variation in the readings since
you're not really measuring a steady DC voltage but a rectified
sine wave voltage. In the case where you add a capacitor but

That's why the voltages still have to go to 2 separate boards, the
Power Supply and the Sound Board Power Supply, to "clean up" the
voltages?

have no load on the voltage, the capacitor will charge to the peak
DC voltage and hold it, giving you an apparent higher voltage than
you want. But once there is a load on the circuit, the voltage will

I see - very helpful info!

decrease somewhat. As for the 6V lamps, this will happen if
you are not measuring the voltage properly. Some GI lamp
circuits run independent of the system ground, and can only be
measured by connecting the meter across the two transformer
windings. That's probably what's happening here. You could

I measured the voltage over the bridge rectifier.

always test it by temporarily connecting one #44 bulb and I'll bet
it will have normal brightness.

I'll try that!
