I have picked up a 127 preamp power supply that is used to power a
couple of 1- or letter plugins for use as instrument amplifiers. It's quite a boatanchor and seems to work OK but I want to replace the selenium rectifiers in it with silicon for safety reasons. There are 5 rectifiers in there. To save me a bit of measurement work, does anybody have any info on function/ratings of the rectifiers or whether Tek issued a bulletin on their replacement? Morris |

I am sure Tek made a silicon replacement kit for those seleniums. I am sure I have a copy of it on microfiche. I will check that out at my next free moment and see about taking my microfiche to the local library and making you a hard copy of the mod instructions for you. I promise to keep the price of my labor within reason . . . Don't let me forget this . . . at age 62, things sometimes fall in the cracks.

Well, Tek made TWO different silicon mod kits for the 127, depending upon the serial number of your instrument. For Serial Number 100-357, it is 040-0217-00 and for Serial Number 358-1409, it is 040-0282-00. There are about 8 pages in each instruction set. So, if you tell me your Serial Number, I will get a copy of the appropriate kit instructions for you. It will cost you about $2 plus postage. Stan w7ni@...
