The Wurlitzer Electric Piano / 200a picking up local radio?
« on: November 09, 2020, 05:58:04 PM »
Welp, I recently did an amp re-build and when I went to test it for the first time, I'm getting local radio coming through the speakers. Stronger when the vibrato is turned up (using the exterior pot and the thumbwheel trim pot on the board). If I turn up the vibrato to its fullest, the radio signal is *very* strong. But even at lowest volume and lowest vibrato, the radio signal is present coming through the internal speakers. I have not tried using the aux out to see if it still happens (I don't currently have an amp to use).

Anyone had anything like this? Did I install my grounds incorrectly perhaps? I read several times that to reduce hum you should find and eliminate any 'ground loops' and that the stock Wurlitzer ground scheme is not very good, but when I look to find exactly *how* to find and eliminate ground loops, the info is from electrical engineers and it's all jargon...

Thanks!

The Wurlitzer Electric Piano / Doing re-cap and confused on C26
« on: October 31, 2020, 03:02:58 PM »
Hi all, I'm undergoing the VV recap (actually the full amp re-build kit), and I'm looking at the board and seeing that C26 has a resistor (looking at the schematic, it looks to be R59) soldered directly to the top of the resistor? How do I deal with that?

My assumption is that because the VV cap has both leads on bottom, and the original cap has axial leads, I'm just going to solder the resistor to the negative lead on the bottom and it will just take up a funkier space on the board because of the way the leads will have to bend to fit?

Just want to be sure.

For Sale / Wanted: Vintage Vibe Restoration Videos 200A

Hey guys, like the title says, I'm looking for any (all) of the Vintage Vibe restoration videos for the Wurlitzer 200/200A electronic pianos. If anyone has any of them I'd gladly pay (a little less) than what they're going for on VV's site. Thanks!

The Wurlitzer Electric Piano / Vintage Vibe Videos
« on: August 29, 2012, 08:33:39 PM »
Hi all, I guess you'd say this is my first post! To be honest, despite having my 200A for about 8 years now (and doing bits of restoration here and there), I never even thought to look for a forum community for EP lovers! I'm just now getting into a heavy restoration of my prized Wurlizard (my first mod was to paint the case a bright green when we still toured with this baby!). I fully intend to buy the VV deluxe amp restoration kit, and go from there. I'm a competent solderer, but my actual electronics knowledge is pretty poor, I made some LED can lights for DJ work a few years back, but that is the extent of it. So on to the real questions I suppose!

I'm wondering if anyone here has any experience with the VV restoration videos for sale on their site? In particular, does anyone HAVE those videos? I'd like to know exactly what I'm getting before making a purchase. Well, I'm looking forward to getting a solid start on this restoration, and I hope to be a minor contributor to your wonderful community here in the future! Thanks, all!

Chris
