Talk about wacky! There are a total of 9 of these machines for sale in the classified ads over on Audio Asylum. One guy has 2, another one has 7.

It looks like they are all gone now.

Thanks John!  I've been trying to sort this question out from the manual and just wasn't getting it....I'm off to the races so to speak.

Thanks for answering my silly question....I've got another one....If I want to convert my PR99's to IEC, do I need to replace 2 recording amp cards and 2 repro amp cards, or is there only one card for recoding amplification and one card for repro amplification....

I see something like this on ebay:  http://cgi.ebay.com/Studer-ReVox-PR99-B77-record-PCB-HS-IEC-1-177-233_W0QQitemZ230096718366QQihZ013QQcategoryZ67812QQrdZ1QQssPageNameZWD1VQQcmdZViewItem
but I'm not sure if I need 2 of them...best and thanks for any advice...Hopkins

There are NO silly questions.  There is just one card for record and one for play: the Repro amp and the Record amp. The IEC Record Amp is 177.233.81; the IEC Repro amp is 177.877.81 (these are Mk1/Mk2 #'s; Mk3's are different).  Each of the cards has high-speed (15 ips) and low-speed (7.5 ips) sections.

I meant to ask...when you swap out repro/record amp cards, do you need to re-bias the machine?  I think I've heard that you don't, but I haven't heard anything definite...thanks!

You almost certainly will need to recalibrate the machine if you install new repro or record amps.  There's no telling what the setting for bias, rec eq., etc. are for new cards.  When I replaced a repro amp on mine, I had to go through a complete playback calibration using a calibration tape.  So I'm afraid the answer here is "yes".
