Leach Amp pcb group buy interest

[tryonziess]

It is getting close to Christmas again and I am willing to run another Leach amplifier pcb group buy. The board is the 10 transitor layout designed by Jens Rasmussen. This is a very nice amplifier and will provide years of trouble free quality listening if properly assembled.
I have a quote from Advanced Circuits for the boards and if we can get to the 100 unit mark they should cost approximately 18.50 U.S. each plus shipping charges.
Pictures of the pcb and other pertinent information can be found under the Jens Rasmussen leach clone thread.
Several individuals missed out on the two previous group buys so I chose to add this third chance. Please respond here on the forum and I will let all know the results.

Hi Tad,

Would you like the next generation for this GB?

AndrewT will be happy to see the way the FB is done in this version.

See pic.

Jens,
I am always happy to see some of your new work. Do you have the files available to be sent out for pcb's.
I would also like to see a jfet frontend layout for this amp. Would be nice to try out.

Who knows what AndrewT will like.

I'm happy to see Jens, and wonder how Rasmussen Jr. is doing.

It is nice to hear from him again. Just in time for toys for all.

I can have data ready within a week or so.... board is about 26 cm (10.2")

Jfet frontend is on you

Jens,
A week or so sounds great. Maybe we can have some units ready to assemble around Christmas time. I have been wanting to try out my new soldering station anyway.

Anyone else interested in some Leach/Jens pcb's just acknowledge here in this thread. The boards are good size so I am guessing around 17.00-18.00 dollars each U.S. for 100 units.

Early in my time in this forum, I made foolish talk about a 10X transistor Leach amp being "small". I beg forgiveness.
Somewhere (was that you, Bob?) a suggestion was made for a Leach board that would include 12X transistor in a snap-off arrangement. The snap-off would be located at the 6X/6X point to make the board suitable for large or small loads...more flexible.

I'd like to encourage the development of the snap-off board. I know others besides myself would use them.

Jens, Blessings on your family.
