27 resistors = $69

[David Root]

I have a small stash of NOS .022uF/600V Vitamin Q I could provide 3 of. Cost me $11 each but, all in the cause of tone....

If you want to try some Black Gates in cathode bypass, I have some BG NX Hi Q 22uF/6.3V and type N 1.0uf/50V. Highly regarded lowest noise audiophool stuff. Usually have N in .1 and .47uF but currently out of stock.

I have a few BG type VK power caps 22uF/350V too, if they would figure in this project.

PM me.

I've been using PRP General Purpose (GP) 1W metal films for about 3 years, and I have also been looking for a new supply of PRS resistors. Dave West's is too limited and they are GP, not the new PR9372 specific audio design metal films. Michael Percy only has a few PRPs so far. I did get some samples from PRP like rfgordon did, their distributor in Phoenix is already bugging me about them!

Also have a bunch of NOS CDE Black Cat mylar film/foil coupling caps, I almost forgot about those.

Anyone try these? CCF60
I think they sound great and are easier to read in a build

here, from a great guy. Also, try the Sonicaps as couplers: just might change your mind about polypropylene.

The Mills are great as grid resistors.

Sorry for the double post... I thought I turned on my Echoplex but it was this instead

I've used the Mills before. Inadvertently blew one, but I had put it in a power supply line, which was probably not a good idea. It blew because I exceeded the 400V limit, not its power capacity. The other one I put in was further down the line, below 400V and survived nicely. I was interested to see if the reduced inductance might make any audible difference. Grid resistor is a much better application!

The Vishay CC60s look interesting. The PRP's only downside is they ARE hard to read. Where does one get the CC60s and how much are they?

The voltage rating is across the resistor, where did you put it to get that across? A bleeder resistor?

CCF60 you mean?
Mouser has them in stock

[David Root]

The Mills was a 10K between the screen choke and the PI, so, no, it didn't have 400V across it. I don't recall the details, but in looking at my final schematic that resistor is now a 6K 2W with about 60V across it. However, I was having trouble in the reverb driver at that time, which turned out to be a missed unconnected reverb driver cathode ground wire. Which is why I now connect each ground wire as I put them in rather than put in all the ground wires and then connect them!

CCF 60s, my mistake. I just got my new Mouser catalog last week, will check them out, thanx for the tip.

pm'ed u david.

CCF60 are great, and are included in this shootout. Mesa uses them alot.

Your first statement may be true. Your second statement does NOT convince me!

I've yet to find a Mesa tone that I really like live. They record well (well, some of them). But I've never heard one in person that I found inspiring.

Just my opinion...

agreed. was only pointing out that they were being used in a production amp. what they do with them, thats a whole other bag of worms.....

Hey Jeremy,

I hope you could tell that my post, while true, was mostly tongue-in-cheek.

I look forward very much to your test results/opinions.

Thanks,
Michael

To be fair to Mesa, CCF60s may be the best at their price point, I can't say, haven't used them, and it depends on your design anyway, IMO. I guess we'll find out in Jeremy's shoot-out.

I've even used el cheapo Xicon carbon film 1/2W in one amp and it sounds great, BUT it was a very simple circuit and I used Mercury Magnetics iron and a nice vintage style Weber speaker, which I'm sure has more to do with it.

Were there ever any results posted from this shootout?

[dynaman]

Yeah, but results were inconclusive because no one could hear the difference between a $5 or 5 cent resistor.

Kidding. I wonder if it was worth it?
