However it's not the point ! I have plenty of much better DMMs in my collection, a dozen Metrix MX 53/54/56, 50.000 counts up to 0,025% accuracy. As crap as it gets as far as DMM performance goes, 2000 count and matching atrocious accuracy. I am broke, and actually just got fired today (no big loss, shitty job and shitty company) yet somehow I managed to have a pleasing TE moment for very little money ! Found this old WaveTek DM27XT DMM. The replacement is a little noisier, I never realised the original HDD was 7200rpm, certainly it was very quiet. I'll probably carry on using it with the spare HDD till it fails too, then maybe think about a SATA conversion. After fitting the spare lower capacity HDD (500GB down to 160GB) the voltages were checked again, all seemed OK, the only noticeable difference was the unregulated +12V, which had increased from +12.14V to +12.23V, this is probably due to the different power requirements of the HDD, Topfield recorders are supposed to be very fussy about which HDD is fitted, maybe this is part of the reason. Before trying the spare HDD removed from the piece of Vestel shit it replaced, a quick check of the PSU rails revealed no problems, most of the original crap Samxon capacitors in the Topfield PSU got replaced in 2011. Some quick teardown pictures, if I had more time I might have bothered cleaned it first. Last week my ancient Topfield 5810 TV recorder box decided it didn't want to read the HDD contents anymore, another WD HDD failure, to be fair it's lasted since 2009 and turning off the continuous "timeshift" recording mode probably helped. Not had a chance for working on any TEA, or much else for a while.
