Nikola,

 The picture of the amp just prior the one of your living room, is that a solid piece of Beech wood?

Nice work, welcome to the forum,

Is this picture? https://picasaweb.google.com/azazello52/Amplifiers#5484166674303512066
Not! This is material from pressed parts.....
/This amp I gifted to my daughter....she lives in Ann Arbor - Mich. Univ./

Yes that is the picture. Thanks I figured it had to be plywood, just wanted to make sure.

Nikola,

Sorry for the confusion, I was replying to Mike Gagne. He lives in Hawai'i and I was just using some Hawai'ian words in my post.

hale = house or building
ho`olohe = listen
ho`i mai = come back

Sorry, next time I'll just say Hi Mike

ZYGI, mahalo for the shout out. The new hale is not pau yet-still finishing but am able to appear more often.
Azazello, I am impressed with your body of work! I hope you are making a living at it.

I will post pics soon.

I changed electr. chock to iron, because I founded that el. chock doesn't avoid big moment energy cross to the amplifier.
It was second try and I decided never use el. chock!
I increased every plate current to 90 ma /more current - big sound!/, and I changed interstage caps to russian ФТ-3 - 0,47 uF /I tried Auricap, Dayton, K73-16/ and result is very, very fascinate and amazing! ФТ-3 is my favorite, I used it in my SE 2A3 RCA!
Uplate = 352 v, fixed bias -65v. For prestage 6E5P - U plate = 190 v, Iplate = 25 ma, Rplate = 7 kohm, R cathode = 100 ohms. U cathode = 2,5 v.. Cathode shunt ELNA Cerafine - 1000 uF /only 8 passive elements per channel!/.

Mi finished project SE exotic tubes 4P1L & PCC88 Siemens,.....U plate-cathode PCC88 = 130v, Ia = 5,4 ma, Cathode shunt "Panasonic" with very clear sounding. Interstage caps K40-Y9 or ФТ-3, I will listening some days and will decide. Output tranies -
big excellence Hammonds 125FSE. Uplate-cathode 4P1L = 152 v, Ia=50 ma, fixed bias - 6,5 v.
Output power is only 1.5 Watts  per channel /triode mode/, but sounding is like 2A3.

Yesterday I decided to throw away interstage caps that I tried /ФТ-3, K40-Y9, Auricap, Mallory..../
and I put interstage transformer Hammond 124B, small, but very suitable for small currents /5-6 ma/ and for tubes with low Ra /PCC88, 6N1P, 6N23P, E80CC...../ Transformer's  primary Ra = 10 kohm.
I used one section of secondary coil. The sound is  a level high and better, very clear, detail, with strong bass. I was very surprised!!
I'd like advise You try it! /Don't forget connect 10-15 kohm, the same, like Ra, short to one section of secondary coil, or 20-25 kohm, if You use full secondary coil to doubling the signal for driving output tube, if it needs, and don't see it's parameter 150-15000 Hz,  I heard very good last string of acoustic bass, and I measured linearity between 35-18000 Hz!/.
BTW....I didn't find EDCORS's interstage transformers in their prod. list...

I tried different shunt resistors for half of secondary coil:
1. If use 15-20 kohm linearity of LF starts from 70-60 Hz.
2. If use 12-13 kohm _____________________ 50-60 Hz.
3. If use 10 kohm _____________________ 35-40 Hz.
Linearity of HF is more 18-20 kHz.
Now I use 10 kohm and sound is unbelievable bright and clear!
Now they cost in http://www.tubesandmore.com/ -Hammond interstage tr. 36 $, but I founded in the same price list, IMO, maybe the same /P-T 156/ for 17 $!
