[pianotech] something interesting and question about a Yamaha

The light in the bottom of the piano is an old trick, used by many older piano technicians who didn't know, or were to cheap, to buy damp chasers. They do about the same thing, except, unless the bulb is less than 50w, it would create too much heat, and concentrated too much in a small area, instead of uniformly across the width of the piano. I would receommend you sell him a 25w damp chaser to replace the light bulb. Also, when he moves the piano, you don't want to move the light bulb, because it will break, as where a damp chaser won't. 

The P2 problem was discussed just recently, but again, it could be that the hammer return butt spring loops are broken. This is hard to see, even for us sighted people. You will need to get your wife, or the customer, to look inside the action, behind the hammer butts, to see if the springs are "up", instead of attached to the loops.

Hi Everone,
I'm not sure if I did thank you who responded to my e-mails the last few times, but thanks again.  The customer with the hammer that's not striking, has to reschedule.  
 
What I found out the other day is this. My wife cleans the house of a couple in our area who owns a Yamaha I'm guessing console. It stands under 5'3" tall.  The previous piano tech. told them to keep a light bulb I guess inside the bottom of the piano the piano. He told her that the heat from the light would keep the piano from getting too moist, but I would think that it would mess up the pitch, dry out other parts control humidity.  Have any of you heard of this?  Maybe someone could shed some light on this lol no pun intended, well not on purpose anyway lol.  I've never heard of this. A light bulb in a piano.  Is this so the mice can see when they are eating the felts?  
 
Also, I evaluated a Yamaha p2 today because he wants to ship it to his daughter about 2 in a half hours away.  It has a couple of keys that don't want to return or repeat well.  If I depress the sustain pedal, they seem to work a little better, guessing tight damper sping?  I think the jack is having some problems as well, strike the note then thunk skips.  Jack pinning perhaps or glueing?  He did say the room does get dry.  It had a dehumidifier rod in side that he didn't know about until I took off the bottom panel to check the bridge, trap work/levers, sound board etc.. I suggested a damp chaser system.  
 
Do any of you service Kensington MD near Washington DC?  I think this piano is worth moving. His daughter wants her son to have a piano to take lessons on. This pianos been in the family for years.  I don't think the would get anyting better for the price he is willing to pay to have it moved there, under $500.  
 
Thanks again.
Marshall
