Thanks Jack,
I'm having a read now.
The more I read the more I like. Both style and info. I'm sure, if I try hard, I can find something we disagree on and it should make for a great discussion.
Once the Olympics are past and I have some spare time to devote to my new venture I'm sure you will hear from me.
love it
I am definitely going to have one of these pages at the new place as I too, seem to be venting of late.

I'm going to build the Jensen version and I'm wondering what type of capaciter to use. The place I was ordering from had three types in this size so I just ordered all three for under a buck. What cap should I use or does it really matter?
They had:
Dipped Tantalum Capacitors (35V) - .1 µF, Dipped Tantalum Capacitor (35V)
Polyester Capacitors - .1 µF, Mylar 100 Volt ±10% Polyester Capacitor
General Purpose Ceramic Capacitors - .1 uF; DIAM: 5 mm; 50 Volt
Also, they did not have a 20K POT so I ordered a 25K POT. This would not be a problem for the impedence POT would it.

As I understood it his intention was to make the source-impedance ('@ sec') low and then let the source imped. as seen by the gtr-amp completely be determined by the imped-pot.

Peter is correct. Besides, if you turned the transformer around the other way, you'd be stepping UP the signal going to the guitar amp by 18dB, which would overload the livin' shit out of it.

I have a pic that some may find interesting...
Could anybody host it for me? :grin:

Or not...Here it is! I may have a higher res 1 somewhere...

from Ed's transformers page we find

trouble is, is that they don't have an online catalog.

...which I drew before I even saw the Jensen schematic. But it's no surprise that they're similar, since it's a simple problem with a fairly obvious solution :grin:
For the transformer, you can use an Edcor WSM10k/150 if you're on a budget.
Funny, the guy who makes the commercial "ReA.." devices usually comes out of the woodwork right about now, guns blazing... Sometimes I think he sits at his PC and plugs the word "ReA..." into Google all day. :roll:

don't be sorry
many of us have had this battle with John.
yes he did pay the money to get the patent.
I don't blame or hate John ... but the US Patent office for granting a patent for something so simple and obvious
they argue about 1993 or 1995
shit this was obvious to anyone in there first year of dabbling with electronics and musical instuments
I did this in the early 80's and our grandfathers did it when the first recording and overdubs could be made on the early multitrackers
I'm sure people had there impedance converters back in the 60's
( Paul and Dave were just young fellows back then )
It's not rocket science .... excuse me ... rocket science was at it's greatest in the 60's
I completely sure the guys new about this stuff back then.
and !!
variable gain tube circuits ... :roll: ... don't get me started
:wink:
let it go
move along
nothing to see here

Yeah... Already moved on. I just had to say something after I put all the pieces together. I honestly wouldn't have cared at all if I didn't see all the retaliatory (spelling) responses and lawsuits he started when others tried making similar devices.
Anyhoo... I made my own and it sounds killer. Long live DIY.

Can the Edcor act as a "drop-in" replacement in the Jensen schematic?

I haven't seen or tested the Edcor
but
in essence, I don't see why not.
