Subject:Re: Pro-145 trimpots

Walter, Walter, Walter.....for someone with a persecution complex, it seems you're ready to go this morning Honey! (Your reactions crack me up when it's a piece of gear you champion, as opposed to something that uh, isn't, um...giving you everything expect.....in case I'm too obtuse, read your posts regarding the NordStage for examples.) But enough of that fiddle faddle.

Ryan, my question to you is serious....having gone through similar (well, actually, even more severe as I didn't seem to have a solution anywhere in sight, not from my own know-how, friends' know-how, manufacturer and dealer know-how) obstacles, how do you feel about your purchase? In the case of the Pro145, I don't possess the handyman skills needed to fix the situation like you did (which of course probably voids the warranty) and returned it for another one. Then #2 shows up with the trimpots off-kilter. This is disconcerting for a couple of reasons: if it wasn't meant to be adjusted, it shouldn't be there. If it is meant to be adjusted, then it should be assembled in such a fashion that that is possible. Judging from your experience and mine, there is a quality control issue at the very least.

Which brings me back to the real point: if you're still loving the amp, then pursuing its ultimate resolution is key, whether that resolution is a fully-functioning, correctly aligned for adjustment "model" via exchange or DIY repairs.

If you're not, my advice is to return it while your return window of opportunity is still open. I've been jerking around with a problem for way too long (6 months) because I really do love the piece of gear....which is ironic because it doesn't work. And I'm starting to regret my obstinance in "getting it fixed" because...well...that window is probably closed for me now.

Anyway, good luck, and let us know how it all ends.

Generally, I agree it's best to rub salt in while the wound is
fresh, likely to sting the most don'cha think? Hmm.. nice.

Old disclaimer: I've advised anyone who's asked and those who
haven't that the speed and transit time adjusment trim pots are the
Pro-145's weak point = don't mess with them unless they're lined
right up directly with the front panel holes and easy to get at,
then be very gentle and careful. If you don't adjust them at all -
the best approach - the Pro-145's speeds and transit times are
already set to match a good used 147 Leslie at the factory.

Sorry you're having a hard time with this Ryan, but I know you're a
good DIY guy ;) Walter
