Fortunately, the tantalum caps I used were not reverse biased as the .1 monolithics never did show up, so I had some teeny teeny 1 uf 16 volt tants in a bag and used those. They are about 1/4 the size of a book match head. They never showed on the bank statement either. I'll take it apart, rework them one at a time & test as I go this time. Tomorrow. Thanks Andy.
