Default what OPT for 211 parallel SE amp?

I'm planinng to build a pair of 211 Parallel SE tube amps. I just don't know what OPT to use? is there any proper OPT for such an application out there in the market with a no-crazy-price? is there member of diyaudio.com who is expert in winding nice OPTs who I can refer to?

How about Lundahl LL9202, gapped for 120mA, and use with configuration for 6.5k load ?

Hi 211 fan,
I'm using LL1691@100mA in mu 211 amp, with a very good result. I know that Lundahl can delivered his opt at your requested operating point.

thanks for both replies. Lundahl seems pretty good. where can I get them? should I order for something special designed for my application?

I'll use 5687 as driver and 6072 tubes and also GZ34s and of curse GE VT-4C/211s
