LF: Big PA

Could you give me info on the little pot-core you use for your driver
transformer in your PA? Material, turns? 

I used a Farnell 559-570 ferrite sleeve, intended for EMC suppression,
no info on material, 16 turns on primary (1.1 mH) and 29 turns
quadrifilar on the secondary. The TC-4426 driving it got rather hot so I
ac coupled it with a 0.33 mFd which seemed to improve things a little.

Thanks, Tom G3OLB
