Is 10.88-10.92 a good enough match?

haha, I can't get any local source for 10mA. I've already got 8 pairs of K170+J74 @7.3mA. another local source only has 8mA

@ZM

My boards shipped today. They will beat the ACA kit, that I plan to assemble first. I will need to get the BOM printed out for the Aleph J, and PSU (and somewhere in there order the universal PSU boards)

Transformer though, 300VA is enough for single toroid? Thinking I don't really have room in my setup for a 2-4 box dual mono setup with dual trannies, although perhaps I do what 6L6 did with bolting 2 transformers together in the one box. Even if the PSU components are in a separate case, the amp case with its 2 large heat sinks tend to be as big as a case to hold the whole thing.

That was Grimberg, not me. It's a great way to do it... He could only get 200VA transformers at the time he ordered, due to the Antek fire.

Yes, 300VA will be sufficient.

6L6, did you ever get your ground loop issue tracked down? I couldn't tell how you had "-in" connected for the SE input and wondered if that had anything to do with it.

Yes, just a layout issue. Short leads are happy leads.

Thanks, something less to worry about by this DIY newbie. The Aleph J will be one step closer to a true DIY project for me. I have built several all included kits now, with the ACA up next. I will be finding all the parts myself for the Aleph J, based on the boards here.

Quite the adventure for this 54 year old orthopedist who started his DIY career building a "crystal radio". I have virtually no electronic experience, other than the last few years of reading forums, and building the kits.

Default friendly reminder...

For you guys about to build this (I've got pcb's coming too), please note that R5 dissipates ~300mW, a .25W rated resistor is no good there. Zen Mod mentions it way back in the beginning of the other Aleph J thread. Sorry if this was already brought up recently and I missed it...

Per channel, or total?
