Yamaha 300K Push-Push Switched Potentiometers

Unread post by banjo » Sun Oct 01, 2017 3:20 pm

This is not a repair, rather a caveat.

I have wrecked two of these items by removing the Fender type knob without releasing the switch first. Put simply- make sure to un-latch the switch before pulling or prising the knob off. The first time I did this it was understandable because there is an unexpected learning curve, but the second time was stupid and caused by having had a couple of beers! Don't go there!

I'm not sure but I believe that Yamaha have ceased supplying these as spares? This is deprecable because they are a very important spare part. Moreover, the two that I purchased were in the region of £25 each which does seem a little profligate. Sadly, this does not appear to be uncommon for Yamaha do not seem to persevere with models even when they have a winner on their books, but supporting their product line with spare parts of this nature seems to me rather important. I would purchase more of them even at the asking price. If I am correct in thinking that they are no longer available, perhaps a word in someone's shell-like might change the situation...

I'm not sure this is the EXACT part you need, but here they have 250k and 500k pots, linear and logarithmic: http://www.axecaster.co.uk/index.php?ma ... cts_id=126

There's gotta be something out there that fits. :wink:

Thanks for the heads-up. I've purchased those before from the USA website guitarpartsresource. They are fine so far as it goes, but the great thing about the Yamaha variant is that at 300K it sits quite nicely between the normal values of 250K and 500K. This means it is better placed as a tone potentiometer on guitars that have a coil splitting facility on humbuckers. Well, apart from the obvious fact that the Yamaha product is better made!

I note that there is a warning regarding releasing the latching switch before extracting the knob on the website to which you linked. As stated, I found that out the hard way (as did my wallet).
