I have used this bulb in several Yamaha units. A T-1 tuner required a 14.5vdc @ 80ma. As far as the A-960,A-760 not 100% sure if you have doubts, that same website has others to choose from . It just worked fine for me. Yamaha (japan) uses weird oddball bulbs that are no longer available so you got to do what ya got to do,give it a go. As for the A-760 what have you got to lose besides $1.20 it will either work,be to dim or burn out quickly.

That is more or less what I had in mind. I'll get a handful of sizes and see what works best.

I heard back from Yamaha and the A-760 uses the same bulb (14.5V, 80 mA). Thanks for the help.

I figured that there was a good chance it was. That part # I sent you will fit inside that rubber boot. Happy thanksgiving day.

Hi widman,
Cool!
I didn't think they were that high in current. I am glad you checked with Yamaha. Never guess when a lamp is part of a circuit and not just an indicator.

I was surprised to hear back from them on such an old piece of equipment. They even suggested checking with the parts department to see if the bulb was in stock.

As it stands, I'm waiting on my bulbs to arrive from Ken's Electronics and the caps to arrive from Digikey.

I received my parts and replaced the caps & power bulb. The lights shine and the amp sings again.

I do get noise when moving a few of the controls. Specifically the treble, loudness and balance control are very scratchy. Also, the Main Direct button (bypasses the control section) is very noisy when pressed. I guess I need to spray down these controls with contact cleaner. Is there a recommended brand and do I have to remove the controls before using it?

Flush the controls liberally with electrosol or similar then get some Deox-it made by CAIG this stuff is pretty pricey but a little goes along way. Radioshack sells some very small aerosols for 14.95 . The deox-it is IMHO the absolute best. Go to CAIG.com and check it out! I think you can purchase it straight from them.As far as removing controls maybe, maybe not depends if you can easily access the small openings on the controls or not.

Hi Dave,
Sorry, I'm going to disagree with you again on this ........

No! You do not want to wash out the protective lubricants (grease) on the carbon track! The noisy part is the wiper and slip ring. A little applied on the slip ring will cure the noise. I use a dropper with a metal tube (small like a large bore needle). If you take the control apart and clean the oxides off the slip ring and reassemble the control, the noise will be gone for a long time. Normally this is not possible.

DeoxIT® contact cleaner is a fast-acting deoxidizing solution that cleans, protects, lubricates and improves conductivity on all metal connectors and contacts. Use as a general treatment for connectors, contacts and other metal surfaces, and on non-critical metal surfaces with severe oxidation and corrosion. If the metal surface is discolored, it is severe. DeoxIT® dissolves the contamination and protects the surface. For reference, DeoxIT® has approximately 20% cleaning action.
