Hi!

I have only two vintage TV projects planned, one was a valved TV with an isolated chassis and parallel heaters and the second is a Tyne–style CTV.

I will be collecting a PTV next Monday, so me thinks it's time to begin my Hedgehog Standards Converter – I've got the PCB and modulator chip laid in already, so my next purchase will be cheap "lab–kits" of resistors and capacitors – photos will be added to this new thread as construction proceeds!

I have downloaded Frank's latest software – I ordered the PCBs a few months ago – do I need to reorder a new PCB?

Can anyone advise me if only one PCB layout was released or was there more than one?

So far, I've heard of Hedgehog I, Hedgehog II and Hedgehog PSC!
