The Wurlitzer Electric Piano / My 200 just got a warneck/retrolinear!
« on: February 16, 2019, 02:33:41 PM »
The wurli I have been working on overhauling just got an ep200 board and a set of reed shields from retrolinear, and I am impressed. I will admit I still have some work to do in the keybed/easing bushings (those tools/shims/rail felts are on the way), but the amp rail is now basically done, and it sounds great! Ive done all the amp rail modifications one at a time to kind of gauge the differences and draw the process out a little (I like to tinker). The first thing I did was make a new pickup cable out of some xlr and an rca plug/electrical terminal crimp ends, that alone was a big jump in noise reduction, then I twisted and foil covered the ac input lines from the transformer (I actually unscrewed the transformer and flipped it 180 when I did this as it added extra legnth to the ac lines, and also added an inline fuse holder), those two things alone (pickup cable/transformer mod) were very very effective at killing hum. I also installed new speakers after the transformer mod, because I like to party. Last night I removed my damper combs and added the reed shields, they fit very well and removed a touch more of the noise. The reduction in noise in each step actually seemed like it made the amp “louder”, although I am fairly certain this perception of more volume was more related to the fact that there was less background noise after each step. Although when I would power the amp on there was still crackle/hiss (which I imagine was some of the caps on the original amp charging up), it sounded good!

This morning I installed the new amp board, and I will say that it actually IS louder than the old board. Its not like plugging into an external amp loud, but for sure has a much higher output than the old amp. Tonally it sounds more clear, or maybe more full range as the original amp sounded pretty dark in comparison (which could also be due to component age). The vib sounds as youd expect and its got some really nice bark to it! Its also so quiet in terms of noise floor its hard to even tell its on when at rest. As a package deal with the shields the retrolinear kit is a really nice upgrade to a stock 200!

The Wurlitzer Electric Piano / Damper setup on a 200.

Hi all,

This is my first post, but i will begin by thanking all of you folks for the wealth of info this forum has to offer. I bought a project 200 and tore the whole thing down, did the protek lube job for all the action points/damper combs (big help!!), cleaned all the keyposts up and polished em all with flitz, cleaned out all the dust and dead spiders,lightly brushed the key bushings with a tooth brush, and put it all back togehter, not only does it work, but it actually works better than it did before i messed with it!

The main hangups i have with the project at this point is the dampers....the previous owner i think made some “adjustments” and ive been tryin to follow protocol in terms of the service manual (i work as a guitar tech/keyboard tech for touring bands so im not a total greenhorn, but i know more about guitar work). The first issue i had was that the bass side of the dampers were all working great, as well as the first 4 or so of the trebel side, no matter how much i adjusted the damper screws on the dampers to try and get them to make proper contact with the reeds it was to no avail. So i thought id adjust the whole damper via the 7/16th nut on the sustain spring/assembly, after giving it a whole turn i was able to get all the dampers set right....BUT now that ive hooked a sustain pedal to it (it didnt come with one) i cant seem to get the dampers to lift when i press the sustain pedal down (i have adjusted the cable in the pedal some for greater pull). When i do press the sustain pedal it changes the key height all over the board (seemingly at random- but im sure there is a reason for this) and the dampers dont appear to lift freely like ive seen in some video tutorials. Could this be caused by the treble half of the dampers not moving freely in the L bracket that holds it to the harp, because it seems to be fairly siezed up on one side....? i know this is a lot of info, but if anyone could point me in the right direction so im not endlessly going in circles with the setup id really be thankful.
