[Jukebox-list] some Wurly 2200 tech questions

[Rick Force]

Hi all,
I have some tech questions for my 1958 Wurlitzer 2200. First off, there is a constant hum when the mute relay drops out. Doesn't change much according to volume, unless turned way up (then it squeals/ goes into feedback). It's not mechanical vibration as I selected an empty slot and the hum was there with the tone arm just suspended in air. Amp has been rebuilt (maybe something missed?) and has been modified to use a Wurlitzer 2700 series ceramic stereo cartridge (wired in mono). I just had a thought as I write this, could a tone arm wire be touching the arm (I believe its metal and not plastic...the arm is from a 3000). I'll have to check that.
   The next question is concerning the Wurlitzer #147 remote for this juke. The juke sounds great (except that hum), but as soon as that original remote is plugged into the remote socket of the 132 amp, the sound is too loud (can't even turn it all the way down, can still hear the music) and the sound quality is bad (not just distorted, but lack of highs...only bass and some mid range). I understand this is a miss match somehow (as the remote is set for the cobra circuit). How do I get that remote to work with the new mods? Warren Rowe who did the mods, said all mods were at the front end of the amp (the cobra circuit) and the back end (original volume control) was not touched. I need this remote as I need to put the juke in the corner and can't get to the back easily. My guess is that nothing needs to be done to the amp, but to the components in that remote. Why couldn't Wurlitzer just have the volume pot and cancel button in that 147 remote without any extra circuitry like Seeburg and AMI/Rowe? The 147 seem too complicated for what it does (several resistors and caps connected to the pot terminals). You would think that all that could be removed and just connect directly to the pot (they use a double ganged pot...looks like a stereo pot, why would they do this in a mono juke?). Thank you, Rick.
