Yes... Deep freeze is my next goal.... must find a suitable cooler... One that goes to -200șC in 1 minute or so.

Now seriously, if you find a good WW provider for resistors in the 2 to 50ohm range please let us know

Possible our two LCR have the same unaccuracy.

I don't know how measures Michael Percy: never asked him but seriously I doubt he have a Lab precision calibrated LCR.

P.S. we can match with a bad LCR but we can't measure well with a bad LCR....
Really true.

I enjoy DIY a lot... now I have a seriously sounding system without the burden of the brand and cost

Hi Ricardo

I have hundreds of wire-wounds in that range.
They are mostly made by either Welwyn or ERG.

500,000 Ohms is difficult to find...
...I have some on order from Japan at the moment.

1,000,000 Ohms is also difficult to find...
...but I have some coming from Tulsa USA any day now.

Cheers.

Si.

I look forward to your impressions. I have the TSSA waiting and the your RIAA is on the bench in planning stages.

Hi again Ricardo

By the way; don't get me wrong on the Polystyrene caps.
The last 2 phono-pre's I made had these, as people do; and sounded groovy !

I just post-up what's on my mind at the time & hope to see what other people think, or have done with the same problem.

I'm also I think, the last person in the world to have discovered eBay !
When I built the last 2 phono-pre's ( years ago ), I probably didn't even consider using Silver-Mica ( far TOO expensive maybe ).

5 mins on eBay now though, & you've got your self a 'bucket full' of top-quality USSR capacitors for 'pocket-money' prices.
I figure the Russian capacitors look to me like the best made available !
I bought Teflon 15nF & 47nF for my EQ, and will certainly try them out ( & Polystyrene as well ).

Some guy posted earlier that he was 'saving up' for some capacitors.
I mean, if I had to eat brown-rice over Christmas to afford a couple of little 'plastic blocks'...
...I would worry that I might just be missing the point entirely.
Which to me ( and you ), is simply about 'listening' to what sounds good.
No 'high-end' pretensions here at Space Egg...
...like you say " good sounding, no brand, affordable system "...
...perfect !
Learnt years ago, it aint about how much money you spend...
...it's about how much time you put in listening & working on 'your sound' !

BOO JAH !

" Aint that the truth "

Cheers

Si.

P.S. The men in 'the white coats' are coming for me & my wire-wounds !
I'm in the WW asylum for sure !

Hi Ricardo

Phew !!!
Men in white coats...
...not come today !!!
But more wire-wounds from eBay did !!!

2 Questions Ricardo.

I have the K72 Teflons...100n 47n 15n
I think...max value available...not enough for output cap.

But I see FT3 as well...higher values I think.
( I will look again today )
What do you like/use FT3 for ?
Any different to K72 ?
Or just different packaging ?

&

What resistors in your 'Wallace Experiment' are the ones you speak of being 'most important'.
Series...Yes.
Source resistors ?
Is that why you asked about 'low value' WW's ?

Cheers.

Si.

I did save 'The Wallace Experiment' schematic, so I have the R position #'s.

I am going to try mine with SMD resistors. VIshay TNPW 25ppm. Will start with MKP 1837 caps and add the RTX later after initial listen. Will use dual SSLV2's and trafos. Prereg in a seperate box.

Hi Si
Ft3 teflon 100n for interstage cap much better than K72... really see throu imagery... the best.

Low value WW: 2ohm, 3ohm, .... 47ohm for Rs (noise generators) in the input stage
