Wurlitzer 146 noob thread
« on: July 15, 2018, 10:34:43 PM »
Just grabbed this on craigslist. The action feels nice, and surprisingly the felts and hammers are looking good. Anybody have any advice for how to go about testing if the electronics are safe? I don't have a power cable yet.

Fixed the link. Let me know what else you wanna see, and I'll add more to the album.


I know Vintage Vibe offers a 140 amplifier rebuild kit, but I'd be curious to see what kind of sound this guy puts out as is. There was a mouse house near the circuit board, so I'm a bit concerned about that.

And dude, I've seen your Wurly site (really cool), and it says student models didn't have vibrato, but I'm seeing a "vibrato" knob on the front. Is that just mislabeled volume?

Yeah, I see the mouse nest there.  You be careful as you clean that up.

Have you received this yet?

If there is only one knob, it's volume, mislabeled.

It would have been possible for someone to rewire it and add vibrato.  For all I know, Wurlitzer left the vibrato circuit in.

Photos with the badge and closeups of the 8-digit date stamps on the keys and back of the action will be VERY helpful.  Likewise, photos of all of the circuitry, stamps on transformer, and innards.

There aren't many of these around, and the date info is extremely sketchy.

I'd been operating on the idea that "146B" is earlier and "146" is later.  And that they are basically the same.

Thanks for the info, I really appreciate it.

I used a good bit of caution and gloves. I'll get some breathing masks before I stir anything else up.

Edit: I haven't had the time to go open it up tonight, but the serial number is 46224, and the model is definitely 146, not 146B. I'll take pictures of the key codes and electronics soon.

Here's the new album:

Interestingly, the amplifier is a 140-B model one (not too big of a surprise, but pretty neat). Can you tell if the vibrato circuit could be added with a different cable harness or some soldering? My cable harness is totally shot anyway. I'm going to test for shorts tomorrow. And I'll be switching to IEC soon.

Fantastic photos!  Can you get a photo of the 8 digit number behind the damper rods on the treble side of the action rail?  It will probably be upside down, near a number that says something like A-60-2 (or maybe, in this strange case, A-60-4?)

It is not surprising at all that this has a 140B amp in it.  That's normal.

This is from late 1966.

Check the manual for the 140B.  If the amp's resistors etc match that schematic, then it has a vibrato build in.  There are a couple members here who have 146's and can confirm, but my memory is that the vibrato is in there.  Funny that your volume knob says "vib".

@Paleophone,

Thanks for all of the help. I separated the piano and amplifier to work on electrical repairs, and unfortunately was unable to dig out the piano again before leaving for college. I'll be sure to get you more pics and stamp codes, but it will probably be a hot minute.

Long overdue, the code is A-60-2.

I was able to recap the amplifier, and replaced the wire harness. Vibrato is either full or nothing, will have to do some playing around to get that working as well as eliminate some more hum.
