Received my Tayda order for a nobelium. The electrolytic capacitors are mostly JB JFB series. I don't have an opinion on those but I've seen them in electronics. Don't remember if I had to replace any due to swelling.
The one non JB brand is a Chongx for C1. Those are the worst caps I've seen. Replaced many swelled one over the years, particularly in the power supply section. And guess what? C1 is in the power section. I prefer a name brand that is low impedance for C1.
Top brands are Rubycon, Kemet, Panasonic, WIMA, and Nichicon. I think I've listed them in correct order by market share. I will use Rubycon simply because that's what I have on hand. For the film capacitors, I have a mix of Kemet and WIMA. I'll probably use a mix of those two.
The resistors came in quantities of 10 and are cut tape. I did test 1.5k ones and found all 10 are within the 1% tolerance rating.
The Noble guy uses Nichicon electrolytic and mostly WIMA film capacitors. I don't have enough gut shots to tell what the few non-WIMA film capacitors are. He also mostly uses carbon film capacitors, not the metal film ones in the Nobelium BOM. I see one metal film in the gut shot. I'm guessing that the equivalent to the 10M R17 in the Nobelium.
This makes sense because carbon film is usually preferred over metal film for tube amp builders. Probably because carbon comp resistors are what's found in sought after Vintage amps. I have both types but probably will use carbon film except for the 10M part.
In the sticky section, there is a demo of various preamps including Noble and Nobelium. I can hear a difference between the two on the low end. The Noble sounds slightly better to my ears. Perhaps this is why guys on the pedalpcb forums are talking about changing the HPF on the Nobelium. I think they were talking about lowering it slightly. Iirc, from 90hz to 70hz or so. The member there that said he designed the Nobelium (can't confirm that and this is the Internet) at the same HPF value as the Noble. No mention of the slope though.
