Default Re: Thorn 850 chassis - tuning problem

A few more,

Pic 1 shows the timebase chassis recapped but not the IF.

Pic 2 shows the set running with the faulty FOPT, it was arcing internally, luckily I had the correct transformer for this set, a C core type in the spares box

Pic 3 shows the new transformer connected with primary and secondary around the wrong way hence flyback lines.
Pic 4 shows results with the connections corrected but still looking poor due to the original capacitors still in the IF deck.

Cheers
