Hello! I could get now DynaMight 4pcs boards version 2004. Does anybody know is there any difference for balance amplifier between: DynaMight and Susy Dynahi v 1.43?

There are custom TVCs from some Russian DIY master. Those one are balanced.

I tried to buy 2SK216 here: wehavethatitem https://www.ebay.com/itm/283871974560 also fake, seller agree on refund

Does anyone knows where to buy 2SK216 8 pcs?

I used 3 different connectors, different for AC and DC. Something like this: https://www.aliexpress.com/item/4000011885330.html?spm=a2g0s.9042311.0.0.27424c4dG8z02S https://www.aliexpress.com/item/32814240840.html?spm=a2g0s.9042311.0.0.27424c4dG8z02S

http://www.cardas.com/chassis_wire.php Good choice who likes musical, audiophile sound. In my TVC (volume control) I used replica of Nordost Valhalla 7N https://www.aliexpress.com/item/33015770781.html?spm=a2g0o.detail.1000014.2.38516491jh2RYs&gps-id=pcDetailBottomMoreOtherSeller&scm=1007.13338.183346.0&scm_id=1007.13338.183346.0&scm-url=1007.13338.183346.0&pvid=923f90b3-f4d5-43e1-9930-31951a834e44&_t=gps-id:pcDetailBottomMoreOtherSeller,scm-url:1007.13338.183346.0,pvid:923f90b3-f4d5-43e1-9930-31951a834e44,tpp_buckets:668%232846%238109%231935&&pdp_ext_f={"sku_id":"67149102531","sceneId":"23416"} Balanced, transparent, not colorized sound. Good choice for internal wiring.

newdocuments - downloaded ok now

For my HiFiMan HE-6 were made custom cable with pure silver + UPOCC copper, proportion 1/3. And it sounds balanced and transparent at same time.

1. boards - ok 2. documents - has 311 errors:

I am in process of collecting parts for T2. All available except those one: KSC5026MOS IXCP10M90S And time of delivery always move right. For example for IXCP10M90S it was around 04/2022 but now in both shops mouser, digikey phrases like this: It took some time 😪

I am using modified HE-6 with balanced beta22. Sounds also great.

Good approach 👍 I also trying to buy a litte more, but not too much. From my practise all projects completely unique. So parts are not shareable. I built several general amplifiers, balanced beta22, some DACs and so on. As for repairing: mine projects are very cool and I am trying to build them very reliable, so don't need to repair them. If realy something will broke, I will better build new more modern and more performance gardget. This is from my practise of 8 years in DIY. So in conclusion: if extra parts doesn't costs too much - then buy them, otherwise exact count or +1. But anyway: it is usefull to buy 10m90s and fill excel with extra inventory - good idea.

Yes, you are right. But without IXCP10M90S all work is useless. May be it make sence to buy maximim parts now and then the rest of another. Because when IXCP10M90S will be available, could be absent another items. The question that it could be loose some money on extra shippings.

Tried to estimate possibility to collect BOMs for T2 on mouser. First struggle was with MOQ=100 of resitors 273 Xicon MF-RC. Second step is long lead time. Some examples: 595-LF353P 512-KSA1156YS 747-IXCP10M90S 512-FQPF8N80C 512-2N3904BU 655-RT424012 512-BC547BTA 512-KSC5026MOS 512-FQPF8N80C 512-2N3904BU 863-1N4007RLG Baddest times for DIY arrived 😅

PM me if needed gerbers or boards itself.
