Integrated or Power amps compatible with both EL 34 and 6L6 tubes

VTA 70 from tubes4hifi.com

Actually there are a lot but Primaluna comes to mind, especially for someone who wants a more plug and play experience. However what is important to know is what speakers will this amp be driving and what general sound qualities are sought. 

Decware ZMA is a great amp. 2 yr waitlist. but they show up on the preowned market. I bought one and used it 18 months and sold it as I’ve gone SET. Built like a tank and very reliable. Best 4 tube bias system I’ve ever seen. Sounds great.

OBTW, compatible with a lot more tubes as well.

Triode labs / Finale Audio i believe makes a 6L6 amp. 

Audionote makes many EL34 amps. AudioNote kits also. 

Ayon another.
