Zenith 7H920 AM/FM set 7 tube
#24

just got the filter cap section re-canned up.
i ended up using all 160v because of size,,,, but the 160v ones i used are all 105degC rated which should help with the possible inrush and our modern utility potentials but...... if it does not, i have it set up so that from now on i can come in from the top and replace with some of those fancy shmancy tall skinny reditions that have higher voltages.

i used 1) 160v 100pf & 3) 160v 47uf caps to fill up that short but wider can.

I have not measured resistors yet... visually there are 2 that have a more lacking appearance than others but.... that means nothing. i will make time to do resistors next but at the moment i am hot to trot to see if these filter caps rid myself of the gargle noise.... i am betting yes .

tomorrow i will be firing it back up. i had an unexpected dial string failure so i learned how that installed and discovered i and easily adjust the needle if it happens to be off., otherwise at the least an AM band alignment will be done.

if it all works ok,, then i get to polish the outside and such then put it up on its new spot on my shelf in the garage.
