They liked thick film resistors in SIT amp as load over wire wound also.

@Dario
Thanks for the info.

As I was placing an order with Mouser just now I noticed they ran out of 2SK170B

I've had a similar experience with the output resistor of the MyRef...

Between Caddocks MP, Xicon cement wire and Mills MRA the Mills where the less detailed and more confused.

I can't figure out why I didn't tried them earlier on the DCB1...

Take in account that those Caddocks need an heatsink, particularly if you go higher with current.

This one is suitable for 10R and maybe also for 3R3, but it should be verified:

532-577202B00

In this moment I'm using them without heatsink and temperature is 47C

How's everyone enjoying their DCB1?

Been having a blast with mine these few months, it's simply wonderful. But the time has come for me to take it one step up, hehe.

I'm ordering a TKD 2S2511 25k attenuator to replace the valab/gigaworks stepped one i've been using. i still don't trust the chinese fully

I've read that the 25k resistance TKD lists is for BOTH channels, combined. Is that the standard naming system? I've always thought that it is PER channel. Correct me if i'm wrong.

I'm looking at upgrading the resistors as well. I've followed some of the posts and want to confirm if the most critical resistor spot are the 220R? TX2352 are going to cost a pretty penny, i don't think i can afford those. I wonder if swapping all the resistors out for PRPs is a good idea? Or maybe one of the cheaper caddocks like the MK132/MK930 for the 220R and PRP for the rest?

By the way, anyone knows why percy only has 221R, no 220R? PCX is the opposite. Or can i use 221R as a substitute for 220R?

220 is from the E3 series of values. That makes this value freely available for many different electronic components.
221 is from the E96 series of values. That makes it very rare to be made or kept in stock for any electronic components.

Yes, it can be used as a substitute for a 1%, or 2%, or 5%, or 10% tolerance 220r, but not as a substitute for a 0.5%, nor for a 0.1% tolerance 220r.

The amp is completely built up, the only thing I'm struggling a bit with is the attenuator. I have a 10K ALPS lying around but want to order a TKD, still haven't figured out if it will be a 10K or a 25K. Any suggestions?

Regards
