Corby- That's interesting to know that somebody has performed the conversion at least once before.
I have a 5060 "donor chassis" and maybe that would be the one to try and see how I might fit an A11 module in place of the A20. Thanks! -Brian, WA1ZMS -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of corby d dawson Sent: Tuesday, January 08, 2008 11:48 AM To: [email protected] Subject: [time-nuts] 5060A acoustic noise issue Brian, I once obtained a 5060A that was used in the time and frequency lab at HP. I guess it had sentimental value to them as they kept it going long after the 5061B had come out. It had a newer tube in it and more to the point it had one of the later 5061A/B style A11 oven controller modules installed. This provides DC to the hot wire and no acoustic noise! I can't remember where they shoe-horned it in as it is a taller module than the 5060As. These A11 units are obtainable and the modification would not be daunting.
