Attention HIGH Voltage can be lethal

Pay attention when handling ELECTRIC EEL

Love the flux capacitor!  Where do you get them?  I can't find them at Mouser.

Hmmm. I don't see any dark-emitting diodes nor write-only memory in there.

You have either to get them on the black market or build them yourself.

Use a ground stake to poke a hole through the surface, like they have in the schematic.  (http://serve.mysmiley.net/winking/winking0001.gif)

It looks like a Volkswagon bus fix-it manual that was popular in the 60's and 70's.

I love that schematic.  I've posted this here before but the Rane Pseudoacoustic Infector is pretty funny too.  Be sure and read the cut sheet.

I was impressed by the detail of this schem and set my self the task of adding another quality build to my ever growing amp collection. My build was slowed somewhat as the parts list contained components not readily available here in australia.I would liked to have purchased the PT from doug's great range of PT's but my calculations put the required voltage just above anything he has. I hit the internet and found a local supplier with the goods. I was a little put back at the price but with help from the bank manager i was able to make the purchase. I was stumped to what chassis i would use, i was thinking something along the size of a shipping container.( as we know a 20KVA transformer takes up a bit of room :wink:)I must ask the usual dumb Level 1 question, Please i'm still learning, where does the power cord connect :sad:
Thanks for your on going help.

The power cord must be hooked up to a lightning rod on the tallest peak of your castle, and it can only be ran during a severe lightning storm while being supervised by Dr. Frankenstein. This must also be factored into your transformer choice and the specifications of your flux capacitor.

I submitted the schematic in an italian forum

one member of that forum has a council for an improvement modify

must add this component

We could make a Rub Goldberg Amp and have it work

Like Jumping Cables and a 6 volt Battery for the heaters
Paper cups and wire for speakers
Make caps tin foil and paper Scotch tape
Resistors Pencil leads

Use the K.I.S.S. Method

Keep It Simple Stupid
