Hello,
I've found the oscillation this week. it happened between Antenna and RF stage. i've put a steel plate beetween the two stage and the oscillation stop. This morning, i've seen thaht I've forgot to put a small capacitor of 1800µµF on the primary of the longwave transformer, and I think that's the reason of the oscillation. i will try this evening to wire it and we'll see.
the next step is to wind the 2 audio transformer. I can buy it in US but with the shipping charge.... And winding them is a great challenge.
I start restore the cabinet and I see that the speaker is really a philco model as you said. This speaker sound great, with lot of bottom and it's in good condition.
best regards
