For interests sake how much were you looking to get for the preamplifier?

Any photos? The 2sK134/j49 should be Hitachi's.

How much are you looking to get for the TA-477 amplifier?

Dear Housing,

I just opened the DIY amp for you, but sorry to tell you that the MOSFET transistors are the Hitachi 2SK135/J50.

The 120W amp is exactly as displayed in this website: http://www2.plala.or.jp/takatsugu/PARTS.htm

I haven't replaced anything since I bought them new from an electronics shop, however. Instruction sheets specify that Q10/11 could be 2sk134/135; Q12/13 could be 2SJ49/50; the factory version used the higher rated k135/j50.

I am expecting HK$450 per channel. You know the Japanese website is selling them at a whopping 15000 yen a channel. Pickup is available since I am leaving for Hong Kong in two weeks.

honinbou · 1st April 2007, 05:02 PM

2SK135

Tom,
Is C$60 + shipping within BC fair enough?
I don't think shipping would exceed $15, but I have to check with the post office first.

Transistors in the line/RIAA sections are 2SK81/J40.

and the Alps black beauty pots
btw the spindle rods have never been cut short.
