Yamaha TA-25 & TA-50

Unread postby Buzzard » Tue Feb 16, 2016 6:47 pm

Yamaha TA-25 and TA-50

So far there's not much online info, so I'll share what I've found, hoping to gather more info.
Unlike the other TA amps, using the "natural sound speakers, these two have "ordinary" 12" cone speakers.
Production start: 1966 :idea: http://europe.yamaha.com/en/products/mu ... hronology/ :idea:

The specs:

TA-25 (pictures found in 3 expired japanese auctions, actually from the same seller)

TA-50 (only two pictures found so far)

Hi Fretless , Welcome to the Yamaha Forums. :D

Obviously your amp is rare, but it all depends of the condition it's in, visual and function.
The only TA amp that has pretty much the same specs (but not the speakers) is the TA-60.
The exact specs for the TA-25 and TA-50 can be found above.

:idea: The one pictured looks a wreck, but may very well be a beautiful tone monster. :idea:

:?: How about sharing (a lot) of pictures of your rare amp :?:

Best Regards
Peter

Thank you very much for showing pics. ((i)) , is it ok with you if I use some of them here on yamaha Forums :?:

Yes, it's a very rare amp, you're the first, and so far only owner that I've come across. :D

If you want to sell it or keep it is up to how good YOU think it is.

:idea: No matter what, clean it up a bit and give the black tolex some "vinyl restore spray" (silicone) , it will look SO MUCH BETTER. :idea:

If possible, get a knob for the ch-1 bass, or borrow the one from the power switch, giving the power switch another suitable knob.
Is the ch-1 bass stem broken ? , then it needs to be replaced.
Is there any "scratchy" sounds when turning the knobs ? then the controls need cleaning with contact spray.
Is there any switch pedals included for remote controlling the tremolo and reverb ?

:idea: Make the amp LOOK and SOUND as good as possible :idea:

From there on it's uncertain what it can sell for.
As it is .... my guess is between 50 and 100us$
In clean and fully working condition probably equally priced to TA-60 in same condition, or a bit more. :wink:
If you do decide to put it up for sale, aim high, and be prepared to negotiate down.
It's RARE, but on the other hand, there isn't much demand for this almost unknown amp. :?

:idea: The COOL factor on this amp is HUGE, it was Yamaha's 1966 first attempt on guitar amps. :idea: ((i))

Peter

Yamaha JX-25 Amps

Unread postby Buzzard » Thu Mar 10, 2016 4:53 pm

Hi Joseph.

If you want it for "surf" there's reverb, but no tremolo.
For practice you can use headphones with this amp

That being said, the JX series are fine amps, but I never tried one yet. :roll:

Will a 25 watt amp give you enough volume ? are you planning to mike it up ? is it just for home practice ?
Most important, try it, if it works for your needs and the price is right, go for it. :wink:

Here's a review: http://www.tdpri.com/threads/yamaha-jx- ... ps.279030/


it's up to Yamaha standard and will probably outlive us. :?

Regards
Peter

Thanks a lot Buzzard for your help.
I think I will pass on this one. The thing is that I am scarred of amps^^ especialy old ones.
For reverb, I was lucky to find a fender reverb tank localy, so I don't need a good reverb amp.
As much as I like guitars and can repare/mod them, amps are my black beast (french expression).
My ampeg j-20 is doing helicopter noise those days, and the tech daesn't know what to do... I may try an other shop but I it is very difficult to find somebody to repear amps.
I have also an old Fender 85 wich I liked a lot but it needs work and in my area nobody wants to put his hands on a solid state amp.
I may look for the new technology stuff because I am bored to have troubles with amps and there is nothing more stressfull to loose your sound in a gig.
The Quilters have good reviews in the surf music circle... so I may go this way.
I don't know right now. I need something reliable and cheap, haha.

Hi Frelonvert
I am not familiar with the J20 so I Googled. It is a push pull 6v6 powered all valve amp. The noise you refer to I would call "motorboating" which suggests to me that there is an unwanted oscillation in the circuit. This could be caused by a number of problems but possibly something in the power supply/smoothing stage. But it also has a tremolo circuit which of course is an oscillator. If you switch out the tremolo does it still oscillate badly?

Hi Joseph.

I think old Yamaha amps have proven to be extremely reliable, but I agree that a new amp is better for gigging.

I don't perform, so if one of my amps decides to stop working, I pick another, and fix the broken amp later. No big deal.
That being said, I have, so far, NEVER had a Yamaha amp break down, only when I bought one second hand that needed repairs.

Have you thought about going DIGITAL :?: , that will keep noise down to a minimum. :idea:

Peter

Hello Dd, thanks for your help!
Yes , with the tremolo circuit off there still is this "motorboating" noise. When I put the amp on: no noise, I play gently: no problem but after 2 or 3 chords the big noise is comming and no fading until i switch off the stand by switch. I tried also with or without pedals, it is the same thing.^^

Yes, that is why I was thinking of a Quilter 101 mini, or may be a Yamaha thr10c.

I am sure that the old Yamahas are solid but when you buy used gear, you never know what it has come thru!

The Quilter 101 is quite interesting, versatile and it kicks hard and LOUD for it's size and weight. (Y)



If you decide to get A Yamaha THR , you'll have 5 presets at your fingertips, and 100 more if you bring a laptop.
Also with the THR , you can probably leave your pedals at home.
:idea: For home use use, you have a built in studio and excellent computer speakers. :idea:
