Converting a Bogen CHA33 to guitar amp?

[Pneumonic]

I can get my hands on a working CHA33 but I am wondering if it's worth my while as a guitar amp conversion or not?

I also can grab a Precision Electronics PE30 and was wondering if it's a worthwhile guitar amp conversion project?

Neither will cost me much to grab hold of.

Thanks

Pneumonic,
If I had to choose between the two I'd take the PE first. usually better iron. If you can get both do it and make them different circuits.
So to answer your question, yes!

I've got a couple of CHA33's and like them. You can do extensive mods but on one all I did was convert the inputs to a Fender style. If you do that make sure the jacks are isolated from the chassis or it will hum.

Remove the phono input.
Add a grounded power cord.

I also got a lot of hum and attached new electrolytics underneath the cap can.

They sound real smooth, not a lot of high end. With an overdrive they rock, but not a lot of power, that 33 watt rating is baloney.

You likely have to add a choke to the B+ for more filtering .. around $40.
Those PA's have horrible hum characterics that worked ok for grade school annoucement units ... unbearable as a audio amp.
