Did you try cleaning the contacts under the strips with a quip and rubbing alcohol?

Just adjust the strike line of the reed bar. It should be a simple fix.

Be careful tuning that! They are very difficult to tune and very easy to break strings. If you ever break a bass string do NOT throw it out. You will need the old one to have a duplicate made.
That piano is very inharmonic. The bass especially is difficult to tune! You need to tune bass notes FLATTER than you expect, don't make them sharp or they may break. $$$ to replace bass strings.

The hammer and damper both appear to be working. It sounds like either loose screws or loose glue joint(s) on some part on that key. A loose hammer head or hammer flange screw are the first 2 things I would check. I do not see the damper falling down right away. It seems to be staying up.

I really think it's cold solder joints. They are not always obvious from visual inspection.
Careful resolder the amp board. Don't do this if you aren't sure what to do. In that case, find a local tech.

That is going to be tough to find. I've only seen ONE in the last 45 years. Is it to complete your piano, or to actually use? They arent the sturdiest benches for adults. But you probably know that! Lol

No, it is not normal. Double and triple check every Eb damper. It is very likely one is not seating properly. Sometimes the felt gets crusty and squeezing the felt with needle nose pliers can help.

Usually, letoff too close causes the hammer to block against the reed, and also increases the chance of reed breakage.
If a hammer lets off too early, you have to hit the key harder which can cause the hammer to double strike or " bobble" . Most unserviced Wurlitzers that I have encountered over the years are letting off too early.
You also need to check key dip to be sure nothing is impeding the key travel. (Compare to a properly working neighboring key) Extremely shallow dip can cause double striking as well, extreme dip can cause hammer blocking.

I don't think so since you measure the voltage right where the wires attach. If you are super careful, you can disconnect the + wire from the reed bar and measure, but watch out for shorting it or getting zapped! You can disconnect it with the power off and use electrical tape to tape it to your meter...you can just leave the ground wire where it is. This will give you a reading with no load.

The new Lowe's ad regarding giving military discounts shows a 140 or 145 that is 1/2 painted, and has no sustain pedal. It's funny how they painted the piano but not the legs. There are 2 knobs on the left cheek block, so it's not a 120 or earlier. Silly place to pile books and ukuleles.....

If changing electrolytic caps, be sure you note the polarity, and put the new ones in the right way.
The black stripe running down the side of can caps indicates polarity.
I'm 90% sure wv35 means "working volts-35"

« on: May 05, 2021, 03:33:03 PM »
I wouldn't use a 9v battery to do the test, a 1.5 V is more than sufficient and shouldn't harm the speaker.
For anyone that doesn't know, you can test polarity of an unmarked speaker with a battery. This test also tells you if the speaker is working or fried.. If the cone moves outward with the battery connected, the pos end of the battery is connected to the + terminal. If the cone moves inward, it is reverse phase. If it doesn't move at all with a good battery, the voice coil is likely fried.
This is useful for correctly phasing mismatched speakers.

Yes, I am shipping the tool today.
There is no line out mod for a 120 that I'm aware of. You can make an Aux out, but not line out. There is a difference.
The present outputs are too "hot" to connect to an external amp. VV sells (or used to sell) a small box that connects to your present output to make an Aux out. I know you can DYI with a resistor and a cap, but I don't remember the values. The resistor will be a big one, and I think a 5 watt.
You shouldn't try to connect to an external amp at least until the "death cap" is removed...

The death cap is connected between the AC jack and the chassis ground. DO NOT bridge it! Cut it right out.
A shorted cap is bridged and is a shock/ and possible fire hazard

The Fender Rhodes Electric Piano / Re: Making a stand for Rhodes Suitcase (with stage legs)
« on: March 17, 2021, 05:50:08 AM »
I don't know how your carpentry skills are, but about 40 years ago, I bartered for a suitcase 73 w/no base. I built a box out of 1 x 12 shelving. I did tolex that, and I made front and back pieces out of plywood and covered them with speaker grill cloth. The pedal mounted onto the bottom, and I drilled a hole in the top for the pedal rod. I did have the original power supply for the preamp (but no amp)
I don't think that cost very much to build and it looked great!

The only comment I have is that I personally would just paint the plywood black. I think putting Tolex on it may be a waste of time and money. I've never owned an 88, so I can't help with the flange locations.

« on: February 25, 2021, 02:15:27 PM »
Don't forget that part of the uniqueness of the original Wurlitzer amp is the roughly 150vdc that it creates for the reed bar. A generic amp will not do this. The Wurli is not passive like a Rhodes.

More likely the carbon in the old one was just worn out. You are lucky that you found it fairly quickly.
I had a Wurli with a worn vol pot once and it caused a loud hum at any volume.
I went crazy replacing parts....

There is an inexpensive tester with lights that will plug into any 3 prong recepticle and it will tell you if the outlet is wired properly. They have 3 lights on them.They will light up different ways for correct wiring, open ground, reversed hot and neutral,etc. I think they are like $4 in any home store electrical dept.
He may possibly have an open ground.
Ok, they cost a little more- this one is $6 @ Harbor Freight

Well, there you go. The radio towers...
Are his receptacles properly grounded? I'm assuming he has a 3 prong cord?
Unfortunately, there may not be much else he can do other than move away from those towers....
Probably not feasible...

Well, it's not really line level out, but an AUX out.
Lower impedance (hotter signal)
But yes, it's not just a headphone out.
