Mark Pilant <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- I finally made some time to start looking at my TR-3.
The first thing I wanted to do was check out all the tubes. Of all the tubes I could test (all but the 12JB6; I don't have the adapter... yet :-) I found four marginal tubes: 2 6EA8, the 13DE7, and the 6GX6. These were all tested on my TV-7A/U, and the marginal tubes all had a transconductance less than half the recommended minimum. Now I've started to clean up the chassis. Thanks to the the info on the WB4HFN site (thanks Ron) I've got a good idea of what I would like to do. The biggest question I have is how to best clean the chassis. In Ron's refurbishing article, he mentions steam cleaning the chassis. This sound like a real good way to go, but I'm not sure what to use for a steam source. (I have an air compressor, so getting rid of the moisture won't be a problem.) Also, the (a?) previous owner W8MBH etched his call and SSN on the chassis. I don't mind, but it would be interesting to see if this ham is still around. The call does not appear to be currently in use. Thanks in advance for all comments and suggestions. 73 - Mark N1VQW ---------------------------------------------------------------------- Submissions: [EMAIL PROTECTED] Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost: [EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net ----------------------------------------------------------------------
