Hi Brad,
Thanks so much for the info!  Do you happen to have the specs for the PT-86 transformer?  I did not find a listing for that part number.  At least you've given me some ideas on transformers to look for.  I'll probably go looking on Ebay for some options.  The upright style mounting doesn't bother me.  There is enough room for that.  I'm sure I could probably make a cover plate for the chassis.  I'm not a purist, but I do like things to be neat and tidy as much as possible.
One thing does concern me though.  The existing transformer has an offset center tap. I'm wondering if this was due to the biasing requirements and would some changes be necessary to use a true center tap transformer.  Or am I just making more of this than is necessary.
Thanks.
Rich
