Hi Colinhester,
I do not have allot of personal experience in building amplifiers.
But, I have been told by a few builders that have several amplifier projects under their belts over the past 25 years. Is to use Roederstein Resista MK3 .5 watt and MK8 2 watt in the amplifier circuit, and Mills WW in the power supply. Roederstein Resista's are even desired over Riken CC types.
Michael Percy has the Roederstein resistors, most values in stock.
But, be sure to look at latest pdf catalog where you will need to enlarge it to be able see all the fine print.
Since the Roederstein Resista's are discontinued, he is replacing them with the less desirable PRP brand. He has listed the PRP by each value if his Resista stock is depleted.
The .5 watt resistors are .25 each, and the 2 watt are $1.95 each.
I was curious why Jack Elliano would parallel the 2 watt resistors and oil capacitors in this circuit, possibly for current and voltage tolerance?
Good luck with your project and let us know how it goes.
