[Joe Walden]

Gentlemen;Members or the ForSale-Swap,from Joe in Okla.w5jdy...I recently
was the lucky
(un-lucky)winner on Ebay of a Precision Apparatus Tube Tester Model #612....
Switch"A",marked on the front panel,is broken but possibly could be repaired
if I had a schematic diagram(broken but all the parts are there).. I have
been to several links but have been unsuccessful...I could use some help if
someone has some advise...Please contact me direct at  w5jdy at cox.com or
whiskeyjoe2000 at yahoo.com      I will gladly but a junker or compensate for a
manual or
a schematic diagram.....Thanks for your time... Joe in Okla.w5jdy
