127

morriso2002@...
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. Stan w7ni@easystreet.com morriso2002@yahoo.com.au wrote:

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.
