Hi pbtoko,

It sounds like you live in Japan. Are you able to read Japanese? I'm wondering because it sounds like there has been a lot of forum activity on the TU-879S in Japan so it would be really great if someone were able to tell us what kind of ideas and discoveries people there have made about improving the amp.

Best regards

unfortunately no i do not speak or read japanese but google translate helps a lot I beleive Vicktor of VK music posted a couple of threads and essesentlly i've been rolling tubes and caps upgradeing resistors basically trying to understand what i got here before i start another project. i will post any i find later but i think basically this forum seems to have the tweeks down a lot is local availability and what fits! damn those 100uf 400+V foil caps... i am finding more each day
a company Amtrans sells a couple of upgrade kits on Amazon.co.jp they seem make their own high end audio componites such as resistors and foil caps i have bout a few resistors and some better electrolyc caps but not tried their kits which go for 30 or 4 $ plus shipping. Not sure if they ship out of japan through amazom but the do via the website, oh i guess i shoudl say i am a total newbe at this (more dangerous then i know)

I'm busy designing new speakers. And to determine the Qtc of the cabinet and filter I would like to know the output impedance of this amp. Does anyone know? Would be very much apreciated!

Although everyone seems busy with the successor of this little amp, I tought I'd share my latest upgrade. While thinking about a nice coupling-C, I ended up using the Intertechnik Audyn True Copper. Just two of these, leaving out the first pair of coupling caps (c1 & c2).

The difference is simply amazing! So much more detail and space. Now I know that the old plastic caps really sound plastic... Highly recommended!

Next will be the power cap. And I know that the Mundorf is the save way, but I'm thinking of the Audionote Standard capacitor. Might even fit under the pcb...

Default Amazing little beast

I am glad to see someone else loves the 879 as much as i do, my only regret is not buying two when i had the chance.

i recently had the opportunity to test my build in a audiophiles sound room, comparing it to a pair of marantz 2's the 879 held it own (within limitations 8 watts vs 34) and a few other things)) witnessed by Stig & Jon the "Lyra Guys" of course passing it through a vintage Lyra Connoisseur 4-2L SE pre amp and phono stage was not wasted. lets put it this way i was not embarrassed, even a little impressed it held up so well.

aside form a pair of v-caps i have upgraded resistors added a TKD stepped Attenuator (outside the box disconnecting the original built in one) , i did upgrade the power caps with some slightly better ones of the same design)

the next phase is to do a point to point re wire in a case big enough for some good old school caps. Mumfords, would be great but for now i woudl give something else a try if i can find some that fit.

see pix little beast on the floor next the marantz 2 (with Phillips el34's xf1's and without tubes infront of the speakers.

keep in touch let me know how your power caps fit and more importiany sound.
