AWA battery eliminator issue
#8

Hi John,
1. I haven’t assembled the A & C sections yet. I prefer to make one mistake at a time. 
2. B+ taps are 22/45/67/90/135/180. 
3. C3 is 100 uf, 450 v. 
4. The link you provided for is similar to the sheet packed with the transformer.
5. The taps on the transformer are numbered like the solder points on the board. I just matched them up. 

**My clue that there was a problem showed up with a high reading on the ammeter when I started applying voltage with a variac, followed by a smoking R10 (TWM5J470E). Never a good sign. I pulled the transformer off of the board and will check it out separately. As always- thanks!
- Rob
