I am looking for a source of a very small transformer that will
supply 125 VAC on the secondary and enough 6.3 VAC with current for
1 or two small tubes. Something on the order of a 12AX7 or 2. Small
physical size is important. I need to be able to shoehorn the whole
thing inside of a double outlet box.

Hey OM:
Gits' yourself a old busted VTVM the real old ones used a 6AL5 and a
12AX7 and had to have secondary isolation for the plates of the
12AX7. I remember I picked up a VTVM for 2USD at a radio rally

Hmm, think I got one if I didn't toss it on my last clean up.

Daughter wants a preamp/tone control she can connect between her
guitar and a PA. Circuit design is no problem but fitting it all in
the box she wants it in may be a headache

You can probably find a suitable transformer at www.oldradioparts.com. They
have a $20.00 minimum, but they have a good selection of new and used parts
of all kinds, including transformers. Download the latest transformer list
at http://www.oldradioparts.com/2a23efl.txt and browse thru it to find a
suitable candidate. You'll probably find just about all the parts you'll
need to build the project from the web site; it's just a bit tedious to read
thru all the lists to find what you need.
I've done business with them before and find them to be reputable and easy
to deal with.

If you can't meet their minimum, you might download the Hammond transformer
catalog from and find the part number of a suitable unit, then search Mouser
(www.mouser.com), Digikey (www.digikey.com), Jameco (www.jameco.com), Allied
(www.alliedelec) and Newark (www.newark.com) web sites to buy.
