Don't forget that you can adjust the strike line (front to back adjustment of the reeds) by slightly moving the entire reed bar. You can also heat the glue joint of the hammer that is too quiet and adjust the hammer itself in or out if it is only one key. (See the service manual) you likely want the hammer to hit further in for the sweet spot.

That's good advice, and I'll keep it in mind. The amp goes in tomorrow for 3 prong upgrade and electrolytic caps replacement (and whatever the tech deems necessary.) I'm not entirely sure I'll keep this instrument, but I want to get it in pretty good shape for the next curator. The amp repair might turn the sound of this thing into something I can't part with--who knows?

cheers

The amp is in the shop now and I don't expect to see it again for six weeks. Now, I'm thinking about the speaker. Re-cone or replace? I've re-coned before and it turned out well. How odd of a duck is this speaker? Was it a standard sort of speaker of its day?

I believe it was standard- I think it’s 12”. Just remember the frequency range if a Wurlitzer is roughly 55hz - 2100 hz (plus overtones)
You don’t need a speaker that reproduces 20-20k....

I got the amp back, under $300 in work done. Nice shiny new IEC socket. I'm thinking seriously of selling the instrument. There are still some distorted and loud sounding reeds which annoy me, the damper work I did was good but not perfect (some notes aren't damping and I can't figure out why--I've fiddled with springs, lubricated, even contemplated putting small weights on the offending dampers.) I'm getting tired of the project and I think I need to move on.

With the original cost, repair on the amp, reeds, dampers and miscellaneous parts I'm still under $1000 into it. Do you think I can get that much for it?

Where do you live, if I may ask?  You can PM, I couldn't send you a message for some reason.
