Hi CeeVee,
Me neither I don't have any issue with the switching.
Just right now, I have tested it, switching several times (even very fast - crazy fast indeed) between inputs : Funktion perfekt...

Just wondering watts the matter with yours

Manu

Tested again...seems ok now...guess the relays needed a little exercise.
Tested with switches..."crazily fast" as you say Manu...perfect, aha!!! i thought, it's the remote.
Tried remote...same thing ???????????????

I like these "bugs" that go away by themselves...or maybe i had something interfering with the remote, this was what i was using when i noticed it, ...i was using the remote near a window...or the
fluorescent economy lamps ?

They are switched off right now, i still have daylight.

Problem is that i'm getting to know a working UGS....i tend to see gremlins all over the place until i check everything new !

thanks for the feedback guys, now for the serious debugging of my other UGS module.....

hehe...maybe.

But i got a bit of more substantial news; between last post and this one i checked the other module that did not give absolute offset adjust but gave relative adjust....and even played!

I checked all the bias settings and found out that Q12 Vbe was...0V! so Q12 had given up the ghost!

This shows that even if you follow step by step the alignment procedure for the UGS module, this still is possible to creep in, as the doc says we should check Vbe of the transistors only if the specified voltages at the test points is not met.

I would suggest it is changed to require Vbe testing for all bipolars.

After the absolute offset ( which was 245mv and with the new ZTX droped to 84mv ) was adjusted to 0V, the relative offset which was 0V now showed 42mv and needed adjustment ofcourse.

Summing up: it now plays beautifully !

Now to finish the box...waiting for the pushbuttons....from Scoutone.

Hope this detail can save somebody some pain and disapointment.


next few days...photo sessions! I'll post some nice pictures.

UGS Alignment document....thanks to breizheau.

Although i think Vbe checking has to be done anyway, even if all test point Voltages are correct, as my previous post justifies.

Default UGS Kit wanted

I'm looking to purchase a UGS kit. If anyone has an extra kit, or portion(s) thereof, I would really appreciate a kind note. I can pay for it, of course.
Thanks.
