The PHILCO Phorum

Great job.

As for the 6A8 grit touching giving you more volume.....sometimes that is explained by bad connection in the band switch. I had that exact problem on my 38-690.
Does it happen on all bands or just one?

See both sides of the 1, 2 and 3 coils if they make proper contact through the switch to where they are expected (including the cap of the 6A8).

Thanks! I cleaned all contacts with contact cleaner but they were very "black" maybe was not enough only with the cleaner...I will check that connections and surely I will re-clean all. Any special product different from contact cleaner that works?

DeoxIT.

I found out on my own Deoxit Red, however good, is not necessarily omnipotent. Plus the contacts may simply be not bent right.

I have been checking in Amazon (only suplier for deoxit in Spain) and they have d5 version in spray (5%) and small squeeze tubes 100%, I supose the spray is ok but just to be sure, the first is the one do you use? Thx

Yes Deoxit D5 in red cans. Warning: don't buy those cans with the rotating straw holder - they leak like crazy. Go for a regular spray can.
