Hello,
If you like some old schematics, I've find recently a lot of very old Philips documents, dated end-30's! There is advertisings and technical docs about the amplifiers of those era.
I own schematics (with transformers ratios and windings turns) of amps :
3758 (20W, 2X E449; 2X F443N; AX1)
3760 (60W, E449, E409, 2X 4641, 2X4646, 506)
3750 (20W, F460, 4642, 4647)
2820 (10W, 2XAF7; 2X CL4; AZ1 no transformer characteristics for this model!)I own also advertisings for other "monsters" from the same years (but not the schematics, alas!) :
3771 (110W, E449, E463, 4X 4641, 2X4648, 1561)
2825 (300W, AF7, AL2, 4641, 2X4643, 2X4649, 1561) ...131Kgs!If you're interested by copies, send me a mail to find agreement.
Friendly greetings from Belgium,
Thierry

>I've seen many beatiful German tubes with gold, silver coatings and some large bottles (don't know what they are)and I'm interested in using these tubes to build a power amplifier.
>Would anyone out there please show me the path to identify them and find some schematics and components in order to plan for the project?
>Thank you for your reply, owing to my limited knowledge in tubes, I don't have a particular tubes in mind.
>I saw those beautiful cl4, ae???, ak??? and rens???. I'm wondering whether these tubes can make a good power amp and where I can find components(such as transformers).
