Sometimes it is unavoidable to buy in China, for example Neodymium magnets, but i buy and build most of my stuff in Europe. Some of the best loudspeaker drivers still come from Scandinavia.
Your Block transformers are of the same construction (low profile PCB balanced windings and low radiation) like Hammond you have ordered , perhaps even better with epoxy encapsulation and higher isolation between primary and secondary than Hammond. Many manufacturers produce similar transformers, and I think that they are better than R-core types for audio.The transformers are delayed until december, sorry.
I will use Block transformers for the prototype so that i can cary on.
Later the Hammonds can be fitted and i will listen if they make any difference.
I use low profile PCB transformers made by company ANG in Bulgaria.
I like the blocks a lot and use them all the time. I just thought there was some appetite for something more "exotic". I do not think that the Paradise R3 reacts on the transformer choice much anyway. And then we have the 1H coils. That is a huge size for a low level transistor amps. I know on the other hand that " a good feeling" can have an effect on perceived sound quality. Another " strong placebo effect".
I will nevertheless make some measurements how much quality i get with minimum outlay.

pdul, i have measured some of your trannies and they are around 550 so our measurements are consistent. I have now a lot of good pairs. One was faulty so i can only repeat : measure each end every transistor and do not swap NPN and PNP. It happened to me and i have a lot of experience. I will also finish to select the PNP´s for you today.
I already have 50 good ones.

Sounds good, and sorry for the dead one😱 It is easy for me to keep them apart, since only the npns have cowboy legs and the pnps are strait🙂
cowboy legs, lol.
Yep, the ammo tape ones, they are called cowboys sometimes. Another good one is when we twist leg positions in different pin order equivalents: Irish dancers.😀
Joachim. What brand are those trannies you have? It is rare to see so clear text on them nowadays🙂
I bought them from different places. Mostly Diotec and Fairchild. I mixed brands in my Paradise without problems. When you want exact pairs from the same maker you can sort them by marking. Usually the same batch has an additional number printed on.
I remeasured the "faulty" transistor from yesterday and it works. I may have had a contact problem.
What i meant is that most components have that allmost invisible lasermarking, those in your picture are easy to read.
