Thank you all for the info,
I will order one since building one would cost as much and I would not have as nice a case....HA
I repaired my 4271B I bought for $20 at a hamfest and all it really needed was a few transistors and several relays.
A nice surprise. It works OK on all ranges and on all functions. Aligning it was fun, but time consuming. Does not completely ZERO (on ohms it is about .1 ohm) but I think a test fixture might help this. Right now I am using a Kludge of BNC coax and connectors...
The HPIB does not work, when I put in the last HPIB board the unit stops sampling. Probably a short on one of the ICs. Will see about this later since I really do not use HPIB.
Would like two of the display LEDs but for now the troublesome ones are in the far left position where they don't do much.
