Telefunken vs Siemens EL34

I'm have been looking to upgrade my EL34 power tubes in my amps. Does anyone know if there is a sonic difference between these two brands ( in the EL34 version )? I have studied many photos of the 2 brands, and they appear to be identical in consrtuction.

thanks

They are definitely different, both in sound and construction. Tubeworld.com has some pictures. I have a pair of the "round hole in plate/wings" version, NOS factory matched, that are available. IMHO the rarest and best of the breed of German EL34s.
