Hey guys,
Been a while since I posted, as I've haven't really had much time for DIY for the last year, but thought I should at least report on another successfully built pair after finally getting around to finishing these after leaving them half completed on a shelf for six months. Anyway, I know Pete's only doing special runs now, so unlikely to be much activity, but just in case anyone does come across this again, it's really straightforward but just a few things that might help:
- The input and output pots require their cw / ccw swapping when being wired up. It was mentioned by one person and one person only earlier in this thread, so I didn't do it when I wired my first unit. Once I tried using it, it was indeed counter-intuitive, so I swapped them on my second one and had to go back and redo my first which was a bit of a pain (actually broke a pot, but luckily had a spare), so you can save yourself some work by doing it right the first time. I've never used the original units, so don't know whether that's a quirk of the original units or not.
- The "term" jumper in front of the top transformer chooses between putting a 600R load across the output or not. This info is available in the old 525 build thread, but no-one's explicitly mentioned it here I think.
- Bridge the pads by the meter IC for bar mode. Leave it unbridged for dot.
- The attack mod makes everything good there.
- I used the resistor values mentioned by someone earlier in this thread and the meter works great, FYI.
Anyway, there you go. Haven't used them a lot yet, but doing some rock vocals through one worked instantly, so I'm pretty impressed with them. Also, Pete's metalwork is the best fitting around here FWIW...
Oh, and now a pic:
