    [QUOI ttoo TE=Zackdude;475371]Also is there a way to remove a previous post? I dont see that option. Wanted to remove the picture I attached of the incorrect layout of of the cathode resistor terminals[/QUOTE]

    I too have wondered how to remove a previous post. Best I've done is edit the post withing 24 hrs of submitting it, and either correct it or remove all the text. After 24 hrs, I guess one has to contact MEF for instructions.

    Good to hear you only got a lower current rated fuse to open, and that it wasn't a fault issue. When I have these running into my test speaker in the shop, I've never had the mains fuse blow, mostly due to the very high SPL. On dummy loads, I've gotten close to the rated mains current, but that too won't cause the fuse to blow. During initial testing, I normally have a lower fuse value installed, like 3-4A. I swap it back with the nominal 10A S/B value once I see nominal performance. At any rate, happy to have been of service!

      220ma per tube????? with 660v on the plates, that would mean the tube was dissipating 145 watts at idle. I don't think so.[/QUOTE]

      Woops I meant mV. Measuring as a voltage across the 10 ohm cathode resistors. 220mV/10 ohm. 22 mA.
