> A while back I asked for help in finding a replacement for a blown out
transformer on this amp.
>
> One of my students, Brian Purdy, talked me into sending the electronics to
Ron Holmes (of Harp Commander fame) and having him do what was necessary.
>
> Ron examined everything and found that, not only was the transformer
blown, but also a filter and an output, with the wiring in need of redoing.
>
> After finding out that Ron loves working on Princetons, (one of his
favorite harp amps), I told him to do whatever was necessary.
>
> The amp was returned to me last week. I let Brian take it with him to Jam
Camp where Dennis Gruenling put it through its paces. Everyone loved it and
Dennis compared it favorably to his own gig amp.
>
> Now I am in the process of learning its capabilities and how best to
control that crunchyinyourface blues tone (having gone in a different
direction all these years - more melodic line and pure tone).
>
> What fun. Ron did a first class job in raising this amp from the dead. It
is a keeper. It was also a fair price to pay for the work done. He also said
he did a little mod work on the channel 1 (for harmonica) in a Harp
Commander way  - I don't know exactly what he did, but apparently it does
help with eliminating feedback while approaching a fat tone.
>
> It sounds best to me using a Dennis Gruenling mod mic - JT-30 shell
w/Astatic element.
>
> I recommend Ron for his excellent work.
>
> The amp is model #A08230. Is there any way to find out what year it was
built?
>
> Thanks.
