Make it part of the styling to use a curved or bumped-out lid, and then you can fit the hamburgers under there too.I can fit it but the Sedelbauer power trafo would pressed against the lid making a small bump in the lid. (snip)
Keen eye. I just discovered it. Guess I should repair that. And I am fresh out of kapton tape. I will use a silicone frying pan pad as protection in the future. Heat resistant and durable. What else can I repair it with?
The Sedlbauer comes with a built in plastic hole where I can just fasten a screw and a spacer. I will get a strong L-shaped piece of metal, the one I have bends to the sheer weight of that thing.
The Jantzen cross coils I will use in the CLC is made up of copper foils. I got the advice not to use it as a choke, because this type of coil may have unwanted capacitance, which regular coil does not have. Anyone heard about this? I would like to use it as it is 2.7mH and only 0.45 ohm and will hopefully not get hot and not have problems with saturation.

Okay, the protection plastic on a Sedlbauer is about as heatresistant transpaent package tape. So I will repair with package tape.
I just got a reply from Erse audio and their similar Foil Q and he says: "Yes we have many clients using our foil Q in power supplies as a choke." Although I would have been really surprised if he said "No! Don't buy our product!"

Just wondering if these https://www.madisoundspeakerstore.com/steel-laminate-15-awg/steel-laminate-3.3-mh-15-awg-inductors/ would work. They are relatively cheap.
It's not on his website but I believe Steve at ApexJr still has laminate core inductors for cheap: 9mH (~0R6 DCR, 19AWG) for $4.50. Give him a ring!

3.3mH 0.185 ohm with coil vs jantzen crosscoil 2.7mH 0.45 ohm. I think I will try the foil coil. I read that the prefferable choke for a tube amp is 5-10mH, together with a 50-100uf cap. But that is probably something different than what what we are talking about.

I remember seeing those in some PL X amps
hopefully ,someone will chime in , having experience in first hand
This is what Mr Nelson uses himself in the XA 160 amps

Wow, great info about the XA 160 amps. So with a 2.7mH foil coil air core you get approx. the same DCR as a 10mH cored coil (with a pedigree). I am thinking I should have a coil shootout in the near future.
But. I was given the recommendation by someone that I should have equal capacitance on both sides of the coil, and Nelson Pass uses 6 large capacitors. I haven't seen the schematic, but maybe its a CLCLC??
