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. Jimmie 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 73 OM de n8zu 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 Jimmie 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. -- David dgminala at mediacombb dot net |
