HP23

[Ed Richards]

Good morning Tore;
I quote from Chuck Penson's book :

"HP-23 has on/off toggle switch and pilot light... Choice of 250 or 300
volt...B+ is made by wiring option during assembly. Provides both fixed
and adjustable bias, as well as 6 and 12 volts filaments. Fused 120 VAC
plug. No 240 VAC operation.

HP-23A Has on/off switch with selection of 250 or 300 volt B+. No pilot
light. Provides both fixed and adjustable bias, as well as 6 and 12 volt
filaments. Circuit breaker replaces fused plug. 120 and 240 VAC wiring
options.

HP-23B Has on/off switch with selection of 250 or 300 volts B+. No pilot
light.. Provides only fixed bias and only 12 volt filament. No adjustable
bias or 6 volt filament. Circuit breaker operation. 120 and 240 VAC
wiring options.

HP-23C Has no on/off switch or switch selection of B+. Choice of 250 or
300 volt... B+ is made by wiring option during assembly. No pilot light.
Circuit breaker operation. 120 or 240 VAC wiring options."

Note: It is easy to change the switch in the HP-23 to provide a choice of
250 or 300 volts B+. I have done it.
BTW where are you located? do you need 240 VAC ? I have a HP-23A
available.

Best regards,
Ed Richards
Reno, Nv
