Here is the latest amp for Neogeo333 it is a BL63 driving 6336s it can also use 6AS7s and all it's variants

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

 

 

 

Same amp with 6AS7s and 1633 driver

 

 

The back panel with speaker connections for 12-16 ohm high efficiency speakers. The transformer I used is a monster

to power these power hungry tubes. This picture also shows it using the 3DG4 rectifier instead of the GZ37.

Not yet but I found this:

 

Western Electric 245A first appeared in 1929, discontinued 1979 and is similar to 24A. Filament is only rated for 2 volts @ 1.6 amps.

Plate = 135 volts @ 4.8 ma, Screen = 45 volts, Gm 750, Power out 45 mw

 

It is in the WE we_electron_tubes 1956 manual on page 4

They might work in your 339 with special adapters that have a 2 volt transformer hooked to them.

Okay, as the unofficial curator of The Unauthorized Glenn Amp Museum of San Francisco, it looks like I'm way behind on my Glenn Amp Collection. Tours by appointment only. ;)

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.

Can this amp have taps for speakers as well? So that I can connect my Zu Omens to it? :)

Yes to the 16 ohm tap.

 

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

Frequency response 7Hz to 25KHz

I'm here for the food and beer related posts.  Anything audio related is just incidental.
