Dr Gilmore said that the LED must be 2.1V. I've ordered the recommended Lite-On, and they appear to be 1.9V on my cheap chinese tester. I presume it's alright ? Another question regarding the 3W resistor. The old BOM says 3W, some PCB say 1W. The 5.11k one is stocked at 2W (Vishay/Dale), not 3. And could be obtained at 5.1k (Vishay/BC)... This has already been discussed, but I can't find that info. Thanks

Thanks luvdunhill

Not exactly part sourcing, but I need an advice. I'm planning to put my DAC in a case, but it's using an old fat EI-core transformer. I would like to take the 2-boxes way, but where am I putting the PS boards and chokes ? Boxed with the transformer, or with the signal stuff ? I read that chokes are sensitive to EMI... I'm looking to keep the PSU's impedance as low as possible. Any idea ?

gepardcv, haven't measured it myself, but this supply -despite what they say about it- is very noisy. Some have experienced this at DIYAudio. Personally, I wouldn't dare.

And as they are fat bottomed, they need larger wires too...

Great and ambitious lineup ! I'm also stocking things for this beast, but being a slow builder it's going to take several months... I'm gathering mods ant tips in the thread for now.

I could have been more precise

Yep, sure. But maybe somebody has an unused set or some spares I can make disappear.

Can anybody help me source KG's original T2 transistor ? I don't want to fall into the fake drama.

If it's about 100$, I'm firmly replying for one set. Thanks for the offer !

I have powered up the amp. Bias was very easy to set, but I don't experience the decribed negative tempco : my bias stays quite the same after warming up. Offset is around 40 on one side, and 80 mV in the other, without the OP27 of course. Everything looks quite stable, and the temperature is lower than what I expected. Don't know if I'll wait for a scope before first listening with el cheapo cans...

Still waiting for the first listening of mine What's the project we can peek at the lower left corner of your picture ?

Definitely interested in reading your honest and sometimes rough opinions upon this suspect.

Output transistors not yet properly mounted...

New PSU is running. By the way, which headphone is the best pairing with this amp ?

OK, I guess it will be fine. I was hoping there was a schematic like the first rev http://gilmore.chem.northwestern.edu/dynahiver2a.pdf Thank you.

Can anybody give me the SuSy Dynahi silkscreen ?

I went very nuts with the power transformer. I've just paid for a 50VA "custom order" by Canterbury Windings, with electrostatic shield and a goss band. Planning to put the Klone in a single chassis, I'll see how clean it can be.

OK, so 10k. Thanks for the tip !

Gents, I'm tailoring the last mouser order for my Klone. Which pot do you recommand ? Especially what value ? Thanks and merry Xmas

Sounds good Birgir. As long as they use actual sand...

I'd be in for Joamat's T2 if there is a run.

Looks like a very nice way to use some 6SN7 !

Thanks !

Nice work Muskyhuntr ! Do you guys have an advice for 2N5564 testing ? I have scored a pair at a very low price from a regional seller, I was told they are genuine (and they were the last two in stock). How to verify that ?
