CMF50 Resistors
My default impression of resistor spec's is 1/2 watt.
It looks like the one's you suggest from Dale (although not your preffered sound) is 1/4 watt.
I will order 1/4 watt's if that's okay, since they are cheaper and smaller.
Has anyone tried PRP, and been satified with them?
I dont think anyone except peter has stated that using exotics in 1K, 10Ohms is the way to go. I would not mind getting another opinion or so. I don't want to take too much away from Nelsons initial art work. If radio shack carbon films sound great, I would like to hear that too.😕

To be clear, I never said that.

I used all 1/2w PRP's stood on end and they sound fine. Tommithomas said:My default impression of resistor spec's is 1/2 watt.

Resistor apology
Peter, sorry to scramble my thoughts with threads.
In any case, just trying to get if 1/4 watt is acceptable for the these smaller resistors. It's usually okay to oversize in my book, but not undersize a resistor. But I dont have an EE degree.

1/4 watt resistors will work just fine 😉

Ignorant MUR3060 diode question
Looks like I ordered the MUR3060 from On-Semi with the uninsulated tab.
Makes me wonder how to bolt these things down without bringing current into the chassis. Will the anode pass current into aluminum?
Here are the units.

I have only worked with the gainclone and axial diodes without heatsinks, so dont know how bolting this to the chassis (using a mica insulator of course on bottom, will affect things. Won't some current go through the bolt?
Of course I can hook it up and take the DVM to the thing...

Thanks Peter
I assume something small that will fit through the middle, to contact away from bolt to anode. If anyone has any idea where to get them, let me know. Else I will bug digi-key and mouser.

You can also use an aluminum bar to pin your transistors, that way you only require a mica pad and no through-hole
isolators.
isolators.
Looking for a set of F3 circuit boards....are there any left?
Also any ideas on where to find a pair of LU1014s?

You can find Lovoltechs here: http://www.audioprojekte.de/html/semiconductors.html
As to F3 boards, I'm presently out of them.
Still have one set of F4 boards available.

Anyone have spare of this, let me know.
I needed this to complete the boards. thanks.

Resistor shortages
Sorry for you Digikey Woes.
I ended up ordering Mills @ 1.85 each, and for the Power supplies I ordered Vishay Metal Firms @ 2.12 each from Digikey, although Mills are likely better, I wanted to get the PS together sooner.
The 1/4 Dales should do, and are NP recommended I beleive.
