An externally hosted image should be here but it was not working when we last tested it.

i have allmost finished a new SE amplifier with this tube
the sound is great for a RF pentode like GU50
i still have a little work to do at the case design
for now it's looking like this:
if somebody it is interested in can provide Output Transformers for this tipe of amplifier for 35E for 1 piece

hi
i don't understand verry good what du you want to say with " bifilar wound"
teh air gap si properly calculated
i'm sorry but i can not provide covers
the detailes for the opt transf. are:
section: 14 square cm
P1, P2=1400 turns / 0.23mm wire diameter
S1, S2, S3 = 53 turns / 1 mm
S1 - P1 - S2 - P2 - S3

Do you mean the sound is good for pentode output without negative feedback?
GU-50 are decent tubes, both for RF and AF. Telefunken engineers always knew how to design excellent devices.

Stiff low screen grid bias helps to any pentode to be more linear.

No dude ! Just monofilar wound !
But the guy is a pro at wounding .
I have build my own PP 6P3S with transformers from him .
Works like magic !
