would this speaker work for an allwave 23

[bruce edward]

Hi to everyone. I am looking for a speaker for an allwave 23 amp.

I have come across one the has a fieldcoil of 955 ohms and a voicecoil of 9.5.

Would this work as a speaker for the allwave 23 amp. I have the amp, but could not really afford

the original speaker

thanks

the speaker was originally used in a console that used pp 45 tubes

Bruce - 

The field value is adequate and should work with an AW23. The VC matters only in matching the output transformer - there will need to be a transformer between the PP 2A3s and the VC, you will need to locate a transformer matching the tubes to the VC you intend to use. There are "universal" output transformers that will match both directions. Be sure to get a transformer that can handle the power/load of 4 2A3 tubes - about 35w. A smaller transformer won't hold up and will sound awful.

In addition to the field coil for the B+circuit, the correct AW-23 speaker has a large 5000 ohm resistor (with a tap ) in the pedestal base which is in the bias circuit for the output tubes. You will need to replicate that big resistor, too.

Study the Scott circuit diagram for the amp and speaker:  pins 3, 4 & 5 of the speaker socket when tweeters not used.
