Title: Yamaha THR5 10-Watt Stereo Desktop Modeling Amp
Post by: bagwellbill on December 12, 2014, 01:48:39 AM
I have a Yamaha THR5 10-Watt Stereo Desktop Modeling Amp and the toggle on/off switch is broken and i wanted to know what kind of switch i need because i did some searches on mini toggle switches and there are DPDT and SPDT 5 amp 120v and all kinds of different ratings for the amps and voltages for these. So does anyone know what rating and letter combo i guess lol i would be looking for?

The amplifier also uses a 15v adapter

1) in what Country do you live?   ::)

2) SPDT, DPDT, etc. refer to different switching possibilities, which will be reflected in number of pins.

Your switch may have from 2 to 6 pins/legs ; post a closeup picture .

3) we don't know whether it switches 120/240VAC (Country?  ::) )  or just the 15V DC supplied by the adapter.

Does the amp have a straight 120/240V AC cable which plugs into a wall outlet plus a 15V DC adapter or just the latter one?

I live in the U.S. I only need an on/off switch the adapter for the amplifier is similar to a laptop charger 120v ac plug into the wall then an adapter box that converts to 15v DC then the amplifier. The amplifier is 10w, it functions on 15v DC. Thanks for the response :tu:

  It looks to be a fairly hefty toggle switch, like Fender style.
I think a Fender DPST part #  0036570000 should be a safe bet, if you don't need the extra pins you can just leave them unused.

Edit: That being said, you don't want to drill out a new amp if the diameter doesn't match, so best to measure and check.  That Fender switch fits 1/2" hole.

its not a large switch at all, its  a mini toggle switch and i'd rather not go with brand names because imo it seems rather pointless to pay for a genuine Fender switch when its a toggle switch.... I just need a rough estimate on what kind of witch i need

3rd time you ask for an answer whith implied adivination, because you don't want to do your homework.

OK, wait until Christmas then and maybe you are allowed to open it.

By the way, I can't understand how an unboxed "secret" gift can have a broken switch.

Well, the picture to me looked like a regular sized toggle, but now that you mention it, I see it is smaller diameter than the jack.
  The Fender switch I mentioned is not expensive at $7.95, I mentioned it because they are easily available, but no matter as it is the wrong one.
  To get the proper switch, as has been mentioned, you need to measure the diameter of the bushing, and count the number of terminals on the switch.
  Without that information, no one can help you, aside from Yamaha or a Yamaha dealer.

OK.
Pity you won't be able to play your guitar on Christmas  :o

And considering typical holiday delays , you won't get your new switch until next year.

Of course, if that's fine with you , who am I to say otherwise?  ::)

The option is to buy your switch from Yamaha, which different to any other, don't need to open the amp and look at it.

Although it will probably cost more than $7.95 and certainly arrive next year, even if you order it now.

Won't comment on your expressed sexual preferences, that's a personal decision.

you are in over your head boss.   Get a friend over to help you, you got no business putting the switch in if you don't know how it even works.

:lmao:
Hey J M Fahey, Should We mention that the switch is likely to be a pcb mount and the one he has may not fit? So even if he wires the switch the right way it maybe futile as the switch maybe the wrong type.

Not to worry as often the amount of indignance is directly proportional to the amount of ignorance displayed. 8|

I'd say there is a fair chance that it will come apart but may not be fixed until well after new year.
Reminds me of the old saying; You can give a fool the meaning of life on a silver platter and he will just throw it in the bin.
I believe there is a simple fix but I'll keep that for when he calms down and comes to the realization that the advice he has received came from many hundreds of collective hours of hard sweat by very intelligent minds that have seen it all before.
What's that old movie line? "Some people you just can't reach"

Meantime life moves on,,, Phil.

So you are mad we are not psychic mind readers with xray vision.   You want an answer to a question that has yet to be asked.
You wont know jack till you get a schematic and open it up.   A simple google search of 3 pole toggle switch wiring will give you a basic idea...but it's all a guess until you see how its made inside.

And wouldn't common sense suggest....that if you buy the right switch from fender....that a person could simply take one wire at a time and solder it to the new switch?   After de-soldering it off the old switch?      Unless it it a pin type mounted in a board. and if that is the case..there is no thinking involved.

Have a solder gun @40 watts?
Have a de-solder bulb?
Have a mutimeter?

We know you got a poopy attitude.  Leave that behind. Become humble...and learn.

Worst is that they were treated kindly, we tried to help, but asked for some clarification to do so.
And they burst their tops.
Oh well.
