Need to find 300B tube amp use 6SN7 5U4G >25w/ch

[supernut]

After gathering information I found a horn speakers that might be more suitable for Single End amplifer.

So I post the link:

Fostex FE208 Sigma

Jericho Horn Speaker

SPL 96DB

For 30W push pull amp.

Can anyone provide value of Resistor (in ohms & watts) and Capacitor of this schematic, Please?

I think it serve my requirement and not expensive.

I gather information from this web
http://www.mizunaga.jp/cpamp0.hml

and found 6SN7 300B Push pull but no clue about Resistor and capacitors.

SIT-152 is an interstage transformer used for phase splitting. It will probably be a very expensive part.

I don't know the value of 1:2 interstage transformer. Some seller sell them in many value 44, 59, 106 HENRY etc

The price I can found cheaper in Taobao.

Which Henry and resistance for push pull schematic?

For push pull,

I got information that there is no need for "interstage transformer"

just "direct coupled tube phase splitter"

How to put "direct coupled tube phase splitter" in this diagram?

You do not need to reinvent the wheel.
Have a look through these and follow the links.

I have read that an interstage transformer if not high quality (expensive)and designed well can be worse than Capacitor coupling

Just found good schematic and share

6SN7 6BL7 300B push pull

Just found good schematic and share

6SN7 6BL7 300B push pull

What makes this a good schematic or amplifier?
Parallel push pull? 😕

Mr Yannick mahe designed 300b transformer driver as prototype for
Haut-Parleurs Systèmes

This is 20w + 20w that I plan to do

Anyone has schematic of this amp?

 

[supernut]

Haut-Parleurs Systèmes

I need this amp schematic

Anyone has?

 

[supernut]

Another schematic find out.

Just want to share. Don't know which schematic sound better.

I just find as much as possible and share and hope someday, some experts here will give advice about these schematics.

Thanks for comment of Mr. Micheal

So KT88 in PP provide the best bass. I have to think about it.

I fond of punch bass.
