Even if the original resistors in the unit had a tolerance stripe?

I say that because the original resistors appeared to have a tolerance stripe but I couldn't make out the color because the color code stripes were too discolored from heat damage that I couldn't make out the colors they were originally.

Unfortunately the service manual for this unit doesn't list tolerances for the resistors just their resistances and wattages (even though I had seen several resistors in this unit that had 5% tolerance stripes on them.)

Also I do have a box of 150 Ohm 1/2 watt fireproof resistors, would that work in place of the original 100 Ohm 1/3 W resistors if what you say is correct for this situation?

How about the original transistors?

I need to source some replacements but I keep coming up empty handed, as they don't seem to have a modern replacement except through NTE which like I said the suppliers that their website lists that carries their replacements for these transistors are companies I have never heard of before and because of that I don't know if I want to deal with a supplier that I'm not familiar with unless someone here says otherwise.

Unfortunately these transistors don't crossreference to anything that Mouser or Digikey have in their inventory.

I did seem to find a matched set of NOS transistors like the ones I needed (they were the same number as the originals) on ebay for $5 plus $3 shipping, should I try those and see if those would work?
