Mod for Studer A-80 Mk2 Record 10K trim pot -15ips
« on: February 02, 2005, 03:26:49 am »

Is there a mod I can do on the record card for this machine
at 15 ips. I can't seen to bring back 10K enough  on the trim pot.
I am biasing -4db with 499 and GP9.
With the trim pot  all the way down I am still up about 1.5db. at 10K
Years ago Studer told me to change two caps on the record card, the two 1nf caps to 2nf for the use of the newer tapes.
That work fine at 30 ips. It was the same problem too much 10K
From the printout I thought I found the correct caps for 15 ips
When I changed them I got no change.
If I can get some tips on this as what caps and where to look that would be most help full.
Thanks
Jim

All I have handy is MK III/IV info.  Can you post a scan of the schemo?
