That would definitely be a very unique amp.

 

Ultra it may be better to use 310A/B and 328A/B than the 245A.

Yes to the 16 ohm tap.

With all Lundalh transformers no hum pickup at all total black back ground

Frequency response 7Hz to 25KHz

 

Besides the 300B power tube, what other tubes would you build this amp around?

Clayton what you need is a 300B headphone amp with Lundalh transformers

 8 watts out into 4 8 16 40 and 80 ohms Then you will have the best amp

ever made for headphones.

 

Though, you may have directed that to him, interestingly, those are my needs... to name a few. :normal_smile :

And, Glenn and I have been discussing this too.  I "made" him find a low impedance OT which he quickly did.

I would use the C3g but I suppose I could use a 6SN7 or 12SN7

David you are the person I looked these up for

Since I built Tyrells amp with Lundalh transformers they will be the only transformer I use unless it is a OTL.

His amp was the quietest amp I ever built or herd. With fantastic frequency response it gets no better then these.

I am not really for using these tubes they have very low plate current

don't know if I would get enough drive and they have crazy filament voltages

Wow, that's a cool amp.

and a 6SN7 or 12SN7 or 25SN7 / 1633 / 13D1 instead of the BL63 and of course the 6F8G

Finally got to see the amp for the first time.  Its better than I expected.  Glenn, does those 6336 get toasty?  Last time I was testing them I nearly burn my fingers.  Any way you can measure its output power?  As always another beast from Glenn Studio.

Congratulations George, it looks so good.

 

Not a beast but a beauty!!!!!!!!!!!!!!!!

post #5261 of 10214

Thanks Stavros.  Its a beauty certainly.  How about a shot of its inside Glenn?  I bet that would be a beast. 

post #5262 of 10214

That's right George!!!

 

What make are your 6336's, Cetron?

I have different ones that started collecting from last year.  Some Centons, TS, RCA, and a pair of CSF.  Even one from Pinnacle, but its most likely a rebrand from a USA maker.  I dont believe the UK made any 6336 tubes.  I could be wrong though.

This may be sacrilege, but I figured I'd ask here... I see many of the 2359G designs use tube rectifiers, as does the woo 2/22. Does having a diode bridge change the sound that much? Same Q for constant current sources vs the resistor. My current FrankenWA-3 has a current source in the bottom of the OTL output and FREDs in the bridge. I know some dislike silicon anywhere in amp (other than the glass envelope).

I was thinking of doing the same to a WA-2...but it also has tube rectifier that I was thinking of replacing with solid state....which would also get me higher B+ to work with. The other direction I was toying with was to get a second WA-3 and make mono blocks out of them, I also loved your multi-6SN7 concept....hmmm, crazy thoughts I have. smily_headphones1.gif
