Looks like the pogo pin is missing but had been soldered on.
I found it! It did fall out but was small enough to go unnoticed.

Very sloppy solder job !
Can you, or do you know someone that can solder it back in place ?

John hadnt slept for 10 days straight by the time he did this one.
I can solder it. I have a soldering station and a reasonable amount of experience.
Any idea how to find the pic someone posted of what it should look like?

The small part of the pin should point slightly outside of the enclosure so that when you mount the rear plate the small middle part touches the back plate and is pushed inwards a bit to keep some pressure on (there is a small spring inside)
Make sure the middle pin can be pushed inwards and comes back out when released.
Not good if one has to check if the pin is there.

It's embarrassing, isn't it.

Quite possibly , that shouldn't be happening l30 should switch silently.
Did you hear any click sound from the relay while doing it?

Does this happen every time you switch to RCA ?
So even when you have the switch to RCA out position and only momentarily switch to HP ?
Is the loudness of the 'pop' volume control dependent ? so very audible at max. volume setting and not audible with volume down ?
Does this also happens when nothing is connected to the L30 input ?

I came to conclusion that
a) it is in my head
b) I put my right earcup further back because of my glasses
I'm really enjoying this little amp again. Very happy to have it back in my system. No noises when switching OFF/HPA/PRE. It seems to stabilize at 33C. There may be a little channel imbalance below 9 o'clock, which is of no concern for me. Especially considering the 3 gain settings.
My original had an occasional light pop in the head phones occasionally that went away when I touched it. I changed everything around thinking it was my setup but the noise persisted. I pulled it for the HP safety. Apos handled the replacement nicely.
My replacement showed up with the pogo grounding pin broken off. Luckily I pulled the back over a clean spot on my bench and it was found. Thanks to help from forum members that noticed it looked like it had been there, I was able to get the amp back in service.
I can't find anything that doesn't sound good on the E30, L30 and Sundara. Sometimes I think tubes may offer something extra in the mids, but giving up the tight bass control isn't worth the trade-off.
Now, if we could bi-amp head phones like a two way speaker that would be fun!

Yes you should. Actually your whole life should be governed by fear.
Or maybe just take a leap of faith and remember that on the Internet, people who complain on forums are usually the 1% with problems. The 99% others just enjoy life!
Seriously now, there's no reason to worry. Worst case scenario you'll get a refund or an exchange.
I personally have a 3rd amp to buy, and guess what it will be ?... Yes, another L30.
