Hi E/B,

Don't yet have it listed - guess folks would love a piccy, and some panel details - is it Tosh or Vestel  ?   - Chris.

Hi E/B,

But did it do the biz, and if so -  why ?  - just a thought (love them nifty BC337's) - Chris

Hi,

Would have killed for piccies, will prob have 6 in next week and be forced to think after I've phutted all my Sendz Components 70s surplus bulk-pak BC337s -

Well there's still all those cheap 2N3055s - sure they'll take it, but slowly - Chris.
