S.E.X. Kit / Re: S.E.X. 3.0 kit with C4S no sound right channel, voltages off on C4S board

If you have a soldering iron with an adjustable temperature, turn it all the way up.  If you don't have an adjustable temperature soldering iron, then the iron you have just doesn't get hot enough.

S.E.X. Kit / Re: S.E.X. 3.0 kit with C4S no sound right channel, voltages off on C4S board

Hi PB,

Thanks so much for the quick reply! I've been out of town and now just returned to take the measurements.... and miraculously both channels are working right now, both sets of C4S LEDs are lit. So the pin9 DC voltages are 2.25v for each. But that's not helpful for diagnosis now. Naturally these things fix themselves as soon as one asks for help, but I'll take it and now enjoying the sweet music!

I'm assuming the most likely cause is a tenuous solder joint somewhere.
I wanted to still post the pics I had from before I left, and in the hopes that this could help anyone else with the same problem, and if you happen to spy a bad joint that I should target.

Thanks,
Wei

Error found.
The error was in the wiring of the output board. It's a miracle that it played at all. Yes, maybe I didn't take enough breaks and wasn't concentrating.
Now the BeePree2 plays as I expected. Wonderful.
Best wishes

Moreplay / Re: Moreplay add ons - were there still any upgrades planned?

This upgrade barely influences the second harmonic but really suppresses the higher order harmonics that aren't as pleasant to listen to.

This is one upgrade I’m very hesitant to do. The stock Moreplay has some real magic to it that I would hate to lose. I’ll be interested to see what people think.

General Discussion / Shipping status

As of this afternoon all kits are caught up with the exception of the new Moreplay upgrade kit. A few of those are awaiting mica insulators before they can ship next week. Other than that all the recent orders - the last S.E.X. kits,  StereomourII and SII upgrade kits, Pipettes, Subette, Sublime, Otari and Technics tape path upgrades, and some others I am probably forgetting - have shipped or will go out tomorrow.

Eileen and I will be away from the office for a few days next week.

The first half dozen upgrade kits are packing today. We are awaiting some mica insulators that got delayed in shipping. Once those arrive we will be packing and shipping the balance of the first run kits.

Eileen and I will be away from the office for a few days early next week. All other orders are caught up as of this afternoon.

Unfortunately building everything at once make it more difficult for us to help figure out where the fault is.  I would suggest checking the wiring of the input selector switch first. For the preamp to be playing in mono only it's most likely that signal carrying wires have been swapped or shorted between channels somewhere.

Hello Doc B
The first is correct. I built everything at once.
I've now measured back and forth up to and including the TwoQuet and can't really find any faults. The only thing is, I have the BeePre1 special edition for comparison. And the channel separation is much better.
I don't want to describe the sound. Only the one plays over the speakers and at least separates left and right when listening, so it's fun.
Maybe I made a mistake. I don't know. The two plays very quietly. So far so good. Unfortunately, the "bing bong" effect is missing now.
Greetings
Felix

When you say you finished the BeePre with all the ugrades, do you mean you built it with the upgrades all at once? Or did you have it running OK in its basic form before installing the upgrades? Knowing that might help to identify where the problem lies.
