While trying to determine if the speaker for my model 90 cathedral is just not that good sounding (it is a model 20 speaker with an Hammond 125C transformer) 2- 45 push pull output tubes.
I hooked up my model 20 speaker from a restored 20 radio. I was able to just set it next to the 90 chassis and plug it in. It sounded a whole lot better.
What I did notice was the amperage draw when using the speaker with the Hammond transformer was 825mA
with the speaker in the 20 radio that has an original output trans. the amps. were 625mA.
Whew, my question is :
Is the difference in the amp. readings anything to be worried about or is it just the difference btwn. the original OPT and the Hammond OPT?
