hello lorenz I did pulse 5 and run it. There is a problem with the commutator connections. The low battery led lights up continuously.

I am used me60 have schema

Use generic JFET op amp like TL062/TL072

[ashkelon]

thanks #nikodimych
061 is little working but circuit is feeding very fast channel A

Whats the other opamp name for channel A?

[nikodimych]

correctly CA3140. TL061 does not work in this scheme

[ashkelon]

thank you very much #eclipse

[eclipse]

You can use TL061

hello friends
whats this IC name ?

Jose,
I haven't taken it out yet - it has a dedicated box which needs some work done before I can take it outside for tests.
It has been a cold winter with snow till last week so I left it like that after I finished it couple of months ago.
I may need to finish the box and close it so it's ready to go outside, Spring is arround the corner and the heavy snow is now gone.


In-home tests show on-par performance with the other designs I've tested, which is to be expected ofcourse.
It has better audio than the audio of the other circuits - 100Hz - 1000Hz 50% duty cycle, It's not 13Khz as noted.


It's got alooooot parts so replication costs alot time, efforts and parts.


I'm using my own 2-board design which follows the original board designs (top+bottom) and own schematic so I can't confirm those posted here 100%
nor I can be absolutely sure everything is done correctly by me too, but in deed, it does work.


When I started drawing the schematic it was a soup of noodles as I've taken it out from the board designs.


It was one of the hardest things to do.


Original boards are very complex and their design is not optimal, I think it's done to add a level of sophistication so it's not easy to redraw.


Simple MCU can replace more than 50% of the whole shebang.
I guess it's justifing high price with number of components and all this dipped into good portion of resin.
