RE: 150 or 180 ohms

Don't forget that you can use two 330 Ohm 10 watt in parallel to make a 165 ohm 20 watter.

Mouser Electronics has a selection of 330 ohm 10 watt.
That's the way Scott did it for a while and the parts list for the 299A calls out two 330 ohm 10 watt. R119-120 or R209-210 depending on the schematic and that's what's in my 299A.

I don't know what your skill set is but having done a 299A myself with some basic knowledge, lots of thinking things out and consulting the Internet, it wasn't easy because things like having the B+ voltages be high or vary due to different current draw of the 7189's wasn't second nature to me and that threw me off for a while.

Like it isn't bad enough for the reasonably experienced to see high B+ due to the higher line voltages today compared to the schematic voltages that were taken at 117 volts in.
