originally it was actually part of the board. but that was when it was single sided and much longer. does not make sense to make the whole board 6 layers just for the attenuator, so its likely going to end up as a board of boards.

5 minute conversion to LP gas... So my old oven went to 450F. New oven goes to 550F, broils at 650F self cleans at 750F (not that i will ever broil in the house with the weber)

I think i have 5 of the amphenol stax jacks left. I will never use them, so if someone needs them let me know.

They are both part of the stax mafia.

The best solution for this is something texscan corp did about 25 years ago. series mosfet switch to parallel mosfet switch to ground, to series mosfet switch. Good for about 105 to 110 db when done this way.

Pretty sure justin is going to make a batch of the teflon jacks. I'm planning on making a small run of teflon plugs. Once i find suitable pins.

No one beats team stax mafia for speed, quality and accuracy NO ONE

sweet will drop this layout into the kgitsojc board when i finally decide what switching relays to use. Time for some fancy software.

For the kgsshv power supply, it sure looks like the bigger ones will fit on the small heatsinks. I'll measure later. For the T2, absolutely not, they have to be .5 wide.

Erwin from Australia just sent me a wonderful piece of very dense Red Mallee Birl. So i think i will make a few more knobs tomorrow

Found this brand new in the box, never used. Batteries in a seperate bag, and immediately dumped in the used chemicals pile. http://gilmore.chem.northwestern.edu/simpson260.jpg I have no idea how old it is, i figure late 1960's

not sure where the 5pf at 200 volts came from, but that is clearly wrong. needs to be 1kv cap.

Back when oscilliscopes were actually really oscilliscopes, i saw people lift the ground, put them in series with a high voltage isolation transformer, chunks of plexiglass under the scope et all. At zenith this was standard practice when working on the high voltage sections. Complete with plastic knob extenders. These days, oscilliscopes are nothing but highly computerized digital things, and would likely completely blow up with any number of simple mistakes. Isolation circuits can be built that safely do this kind of thing. But i really don't want to show people how to do this. I don't want to be responsible for any dead bodies. I have already been present when it has happened. TWICE. Seriously.

Resistors are uncrossed Dact hole spacing is now .1 Resistor labels fixed Craig sawyers cap additions, and resistors moved.

Maximum thickness with the 2sa1486 and ceramic washer is 12.35 mm, So 12mm is just a little bit too small. If you add a .1mm washer its even worse.

Done

So i got some of the peek screws from andy, and tested them. People... These are what you want. Unbelieveably strong and virtually unstripable.

Its the coffee that andy drinks that allows him to do this. Seriously

storm took out my power for a couple of days, so probably won't be able to respond till power is returned.

If some is good, MOAR must be better.

this is the wire http://www.interstatewire.com/Products/MIL-W-22759-43.aspx

The wire i used is actually labeled. At least some of the colors were labeled. If its actually teflon, and nothing else is as slippery and hard to strip as teflon, then if its the right gauge, its likely to be 600V. The much higher voltage stuff is definitely available, but seems to be only available in red.

The ratings on the 600V wire is 600V AC. Which just barely works at max voltage swing. At least the teflon stuff i use is rated that way.

blubliss has the new power supply board with the silkscreen fixed. The one diode in wrong was in the minus supply anyway.
