O.T. Got a reply from Uriah and he is feeling much better and is making good progress in his situation. Let's keep him in our thoughts and prayers.

wrong move, I guess...

In this case I bet that what made it sound "less musical" is not the (not so much) different value of the resistors, but rather their different construction technology. Carbon resistors usually tends to give a "warmer", "richer", "more musical" touch to the sound, while on the contrary metal film ones tends to give a "dryer", "cleaner" and "colder" one.

For this reason, to get a more "balanced" sound Thorsten suggests to use carbon resistors on solid state gears and metal film on tubes ones.

Thus in this circuit I'd suggest trying to use carbon compound resistors such as Kiwame or similar just about everywhere it's possible.

In general, use the highest wattage resistors that you can fit on the PCB: that will reduce transient thermal effects (distortions). This is particularly important on the NFB network(s), where these (and other) subtle effects gets hugely amplified by the loop gain.

hi unixman,

thanks for the advice but they were both carbon film resistors. caddock 925 the value definitely affects the sonics. as linuxguru says, lower value= lower distortion. but since his lf01 modules that im using is already pretty much 2h dominant, well you can see how that goes.

well, of course it does...

hey
unixman

im sorry. 1k was carbon film resistors. (im starting to lose track of them after too many swaps) thick film caddock definitely had more refinement. notes bloomed more
noticeably also, and there was less grain. this i think i can blame on material composition,
because those are the general traits of thick film resistors. no doubt 1k caddock would be the best choice for me.

Try to retrofit Dario's shunt's. Way better than resistor-zenner.

ive tried it and still prefer 1k resistors. they sound more intimate
