Yaqin MS 12B phono amp- reviews

[Rolli666]

Oh sorry missed the 240 volt info won't work for me.
I think if you put up a full detailed list of mods,parts ect. A quite few people including me would be very happy to have a full mod plan to work with. It is hard to keep track with the mods all broken up into posts. Someone should think about selling a kit for this thing.

Also, is the 4 pin connector from the tranny original, or did you fit it? And my unit is a 240v model so 20R is better for the 5814 (ECC82) heaters.

It gave me more joy because it was my first venture into the tube world. It opened my eyes as to the possibilities of tube sound. I learned about Capacitors, resistors. How a phono amp works. How to bypass a cap and why. For the price, its fantastic and unbeatable. Now, We can't compare a $200 phonostage to a $1200 phonostage. The pair of 47k resitors I have in the Cornet2 alone cost $40 bucks. The Yaqin is highly recommended!

Why not? And are the resistors naked foil? If so, do you know about Texas Components?

Yes, they are Vishay VAR-Series "naked" Z201 Z-FOIL RESISTOR. aka. Texas Components TX2575 or Charcroft Electronics CAR Series.

Here is my video with the Yaqin in all it glory using it as a Phono/preamp

So, purchased it, and he helped me do the mods.

He told me to get JJ ECC82/ECC83(I think).

And he replaced the two caps that looked like this:



With a matched pair of this russian NOS paper-in-oil caps:

It really changed the sound from average to outstanding! It sounds very expencive, but is not.

About the pot, is it a dual 100kOhm? I got a blue alps like that and if it is a match it will go in there.

That's great. I suppose those two replaced were on phono line?
I'm planing to replace all of those blue caps (as someone recommended here before is "must") with the Russians K73-16B, also recommended as great caps.
I was thinking to buy Sonicaps, but these two only, cost more than ten K73

It is the only changes to it, and it's just great! The caps was purchased from ebay(russian guy) and was $13 incl shipping to Norway (batch of 6). They are on the big side and had to modify the bottom plate to make another 5-10mm more space inside.

I've also added some bypass caps in the powersupply. For the price, its unbeatable. This preamp has given me more joy than the $1200 Cornet 2 I have. I have to double check everything and put up the Yaqin for sale. All its doing is collecting dust.

I appreciate much your input about mods on Yaqin, very interesting and informative.
If not the problem could you add some photo of the volume pot that you've added/replaced, or just write which one is it, Japan Alps but what type? Thanks!

[Jadran]

I just ordered new pot. as suppose this is the right type of Alps (and better) potentiometer to replace the original one in Yagin, dimensions not clear but hopefully shafts will fit the same board?
