Wow, very nice!

That's a lot of parts, I hope you didn't have to do any troubleshooting!

Question... It looks like there are mounting holes on the board on the bottom left and right, and you've got something there, but I don't see anything on the top of the enclosure? Where are those bolts going?

Cool, I really like the raw metal look.

And I learned a new word today!

Then it got scratchy and I've been stuck. Thanks !

Have you tried cleaning the pot?

It's sealed.

Awesome!!  

Let us know what you come up with, I'm really curious about solid-state switching options.

I'm a little bit late on saying Merry Christmas, but just in time to say Happy New Year!!

Very nice! That's a very clean looking build.


And bonus points for purple wire, purple = mojo. 

Very nice!

I noticed that you changed Q2 from Ge to Si, did you try both?


Happy Thanksgiving everyone!

Hello,

Yes, I had the back cover on. 

It works now. After replacing Q4-Q10 with 2N3904s, everything is running smoothly. What I don't understand is why the Harbinger 1.5 and even 2.0 still use 2N5088s. Maybe I got a bad batch, but they were definitely the cause. According to the transistor tester, they're all fine. Annoying, because the device would have worked from the start...

Anyway, never mind, now I have a working device.

Thanks for your thoughts and contributions.

That's great Holger!

Reading this makes me want to go back to my Harbinger 1.5... I wonder if my cheap 5088s are the problems. That poor thing has been in an esd bag for years now 

Give it a try, maybe we can help.

Assuming you put the back cover on... haha ...  yeah I think replacing the remaining 2N5088s with 2N3904s would be a good idea.

Huh, I don't know.

Yeah, you could try replacing Q2 and Q3.

Hi Holger,

You mentioned you've replaced 3 transistors, what transistors did you have in there before?

Is it possible Q2 and Q3 need to be replaced?

It seems like every time you replace a transistor, there is an improvement.
