Nice going on the EHHA Bill. Am so looking forward to impressions from this meet. Wish I could be there. The CTh is on a different playing field compared to the EHHA. For eg: I can't take the EHHA with me to India in october but I can take my CTH with me

Aye!..for its size, with a 6CG7 tube in it, it scares me with the level of detail and musicality it can dish out.

Whoa!..u serious...damn! Now there's a meet I would want to be at.

This is my very first PCB layout. If someone is interested, I could post the BOM and eagle files. It's PMillets design and I tried to get it in one layer to diy the board.

Reason for posting this here is as a sanity check. Never did that before.

The distance between traces is 15mil and traces are 50mil wide, to stand the current.

Looks good. Might want to make sure its okay with Pete before you release the gerber files.
I would just personally make it on a perf board. Faster and it works perfectly fine.

Or you can just buy a kit for $24. Just add a transformer.

KIT

 

[sachu]

^^Probably a better idea..parts cost for the DIY one is almost 15$

 

[Lifthanger]

thanks sachu and looser!

the reason I'm doing this on PCB is, because I've finally got some free time, to learn eagle and try out the toner transfer method.

No harm in that. Have fun.

Two things. Making the distance between traces wider would probably make it easier to etch without bridges. Get the electrolytics away from the heatsink. Depending on what you are powering that heatsink can get quite hot.

Sorry to keep you all in suspense- the EHHA is Done Enuf For The Meet (needs final AC wiring) but it's cased. Pics soon - or make you wait til tomorrow!

Oh, Cased AND working ...

 

[sachu]

nooo..post now!!..now dammit

 

[Sherwood]

Man, Bill, cutting it down to the wire. Good show!

 

[wiatrob]

What? I got like six or seven hours left!

Here she is - a bit plain but I like simple...

 

[sachu]

very cool Bill..though was expecting to see the surplus cases.

Now to wait for the impressions to flow.

 

[Sherwood]

You running that K1K SE? What's the output wattage/imp. of the EHHA?

Balanced (I re-terminated Smeggy's). Don't know the numbers offhand, but you can search this thread!

EDIT: Found it - MEGAWATTS
