Hi BlueCrab; thanks again for your input, it is clear to me that you know your stuff! As your entry #275 shows, I still measure 60 VAC. The White Oak mods call for the ctr tap to be connected to the chassis at one point only; the screw formerly holding the terminal strip between the left channel heat sinks. I have just measured the assembled amp again; 60 VAC is on the chassis when the line cord ground N/C.
With reference to the dual 500, did you install a soft start? I ask because I've done a fair amount of research on inrush current on 700's and haven't seen a need for it there. I tend to think the impedance of the transformer limits the current to safe values. Note that the stock rectifier can withstand more than 150 amps.
Hello I just bought a dead TEAC A-3300 SX and this repair appears to have already been made once before. I will have to troubleshoot the problem further. But this is valuable info Thanks. Any thoughts about some common shorts to look for this deck is like new, I want to save it. Someone, probably a less experience tech has been through it the rectifier board had a plastic cover missing on a MY2-01 or MY3.
I re-racked the living room stereo after finally getting all the outside work done and returning to the glorious AC, cleaned up 7 VCRs for repairs and just jammed last night. 1998 Pioneer VSX-D307 is the base.
You commented on my Clair Bros PL 700 project, a few weeks ago (thank you). I see that you are also rebuilding a series II. Did you get the White Oak back planes or the control board only? How is your project coming?
Just wondering what the price is on the Rev G Boards? I probably am going to need at least 3 to start...and probably more later. I have two 700s the Jerr recently built and one other 400 I think has recent revisions......but eventually want to upgrade the entire stable...as money allows...
Man, thank you for upgrading Phase Linear to the best amp on this planet...
