If all the other resistors are 5% then the ones you need are probably 5% (especially if they are the same make and construction as the rest) go with something between 5% and 1% tolerance and you should be fine.
150 ohm resistors are not a valid sub for 100 ohm.
There was much less variety in power transistors in the 60's and 70's if it had enough power and was linear it could be used in an amp, linear devices can also be used for switching (horizontal output duty)....If it had the stones and the price point for the job it would get selected....the tube equivalent is that the 6L6 and 6BQ6 are the same tube only the BQ moved the plate connection to the top cap to avoid Corona and arcing issues with the plate pin on the L6....The L6 was common in audio amps and the BQ was common in horizontal circuits (though it also got used in audio occasionally).

Ok, thanks, that makes sense now. I'll keep an eye out for 100 ohm 1/2 W resistors that are flameproof.
As for the transistors, I'll just buy those NOS matched set for sale on ebay.
