That's a nice trick Steve 

I think they will be alright in this use, will see soon enough

The 2 watt Shinkohs made a lovely difference! more realism to instruments, drums, strings, piano ect' 

Realised before installing the Shinkohs that I still had brass lumps on the input of my amp also (meant to change them ages ago), so in went some copper CMC sockets before the Shinkohs were installed and they made a nice difference and let me hear more of everything, should have done it ages ago like I was going to....bloody brass!

[data]

BTW, was informed that the 2w Shinkohs have a voltage rating of 600vdc.

[stevenvalve]

Do not know but that seems Optimistic

[data]

That's what I was informed of by Chris Johnson, president of Parts Connexion.

Edit: important to note that is a voltage handling rating, not a power rating... as in current.

His response was 600v, I take that as a DC voltage rating.

Waiting on some AB resistors for some positions in my amp, I haven't used them before but from what I read here and others experiences I'm chomping at the bit to install them once they arrive 

[stevenvalve]

Great resistors, but new they can sound a bit dark for a few days, but clean out nicely, i use them in tuning,  in only the right positions till the balance is right. Let us know what you think of them, but only after run in.

[data]

Replacing dropping resistors in the feed to the pre amp valves with these, the current ones are kiwame resistors. Maybe some to replace the balancing/drain resistors that are across the Mundorf main filter caps also.

Trying to upgrade from those Kiwami's that are still in the amp, I replaced some Kiwami's with Shinkoh's last episode

[data]

I'm glad I take heed to what is done here, the AB's where a tad over rated values but close enough and the sound is better layered, instead of a tambourine being more of a single sound you hear all the little clangers that make the sound of it, brushes and strings, maracas ect' all sound better layered. It is a richer sound over all, more natrual.

Thanks to Steve and the KD forums again 

[stevenvalve]

It is a richer sound over all, more natural.

Thanks to Steve and the KD forums again 

Richer and natural, That is what i find is most important and why Allen Bradleys can be great, unfortunately most people lose sight of its importance

[data]

Agreed, Steve, I lost it at one point chasing ultimate detail and only focusing on that, only to loose the body...or meat on the bones, lesson learnt there

Have some AB's to replace the drain/balancing resistors on the Mundorf HV main filter caps, not sure how much difference they might make with a change but as I find components in the PS do show their sound signature often, and especially in a valve amp I'll change them and see.

New Audio Note resistor coming soon, using the tantalum's sister material called niobium. Not cheap at GBP 19.50 a pop but I really hope they sound better or at lease similar to the old Shinkoh tantalum.

"We have a new non-magnetic resistor coming soon. They are 2 watt, non-magnetic but rather than our usual Tantalum resistive layer we chose its sister (daughter material, if you study Greek Mythology) Niobium.

Niobium has never been used in a resistor as far as we know. We looked at its properties and felt it was worth testing, and discovered that it is finer and more even sounding than Tantalum.

As is the case with all of our resistors, they are manufactured using the sputter target process, which makes a much better sounding resistor but is also more difficult to use. Niobium is even harder to use than Tantalum as the temperature co-efficient of this material is far more difficult to control in production.

Its sound is very complimentary to Tantalum if used carefully in sound critical parts of the circuit.

Price will be £19.50 each for the 2 watt version. We do not yet have the 1 and ½ watt versions as the manufacturing processes are still under development, but there will be a 2 watt silver Niobium resistor coming next.

We will have the following values available: -
100R, 120R, 150R, 180R, 220R, 270R, 330R, 390R, 470R, 560R, 680R, 820R
1k, 1k2, 1k5, 1k8, 2k2, 2k7, 3k3, 3k9, 4k7, 5k6, 6k8, 8k2
10k, 12k, 15k, 18k, 22k, 27k, 33k, 39k, 47k, 56k, 68k, 82k
100k, 120k, 150k, 180k, 220k, 270k, 330k, 390k, 470k, 560k, 680k, 820k
