Philco model #20
#7

Hello again fellows, just wanted to ask another question on number 8 Bakelite condenser block it has a .05 Uf cap and in the same block it has a 250 ohm resistor winding , can I use a 2 watt metal oxide resistor or should I use a 5 watt power resistor also would it be better to mount the resistor on the outside of the Bakelite block so it can cool better , the reason I ask because on one of the data sheets I seen it was a winding resistor sounded to me like a power resistor , thanks in advance for any help , all the very best Rick
