OK, morzh, thank you for the tips 
1) Philco model 70 no code, Chassis # below B22,000 that has a pot with 2 wirewounds, one with 250 ohms and the other with 5K ohms, 4-5 Watts. Chassis # above B22,000 has only one wirewound. Model 70 schematics are on http://www.nostalgiaair.org/PagesByModel...013833.pdf
2) I am referring to the Volume pot part number 5039, part number 1 in the schematics.
3) I have been told that we can add some resistors/caps and the radio works normally without the 250 ohms wirewound. Does anybody know how to do this modification?
Thank you very much for your attention.
