Re: best cheap/free scores 1.1
Huh,I checked those 680uF caps and they're the same size a D cell,more or less.
This one is actually pretty decent. One thing I found strange - if you have worked with Allieds (I guess you did - Allieds are actually the half-decent line of Deer,with L&C being the total uber crap line) you should remember that after the rectifier bridge (which mine has BTW),there's a MOV installed. In my Modecom PSU though,that MOV is replaced with a strange PCB - it has two 2.2uF 400V caps (Su'scon SK - not bothering to replace them as I don't have replacements and they're the small size you see on motherboards) and two pink resistors. Could be a PFC circuit,since the PFC coil 2-pin connector is just next to it.
Apart from that,this Deer has anything you'd want - PFC coil (real and really heavy as well),approved Y caps covered in heatshrink (both on the PSU board and on the AC receptacle PCB),EE-25 choke (there's a choke on the AC receptacle as well,but it seems they used a copper choke instead of a EE-25 choke,probably because the space between the Y caps and the X cap on the receptacle (there's just one) is small),and of course thick and big heatsinks.
Just the primary transistors are something I can't find over Google - TT2174. Can those be replaced with 13009's? 13009s are capable of doing 400W with a ERL-35 transformer,right?
