Sent on to @JustAnotherRando this afternoon, he has a PM incoming with pics and tracking.
Received from @Imraan. Took me so long to get through the heroic amount of gaffer tape around the box that I didn't have time to hook it up before having to run out for the afternoon.
I am a photographer you know...I LIVE for gaffer tape
The amp is now on it's way to @Lyer25. Many thanks to @Magnetostatic_Tubephile for arranging this. I also liked the choice in packaging materials- I have kept one of the Lidl catalogues in a mysterious (Eastern European?) language at home to confuse the hell out of my wife when she stumbles across it later. Catalogue has been replaced with somewhat more conventional and less entertaining packaging foam
I used the EH tube most of the time, and only very briefly tried the two others. Couldn't get the biasing LEDs to balance out with the Gold Lion tube, not sure if it was me or the tube.
That Lidl packaging was put there by the previous owner, should be in Czech language. Maybe your wife will get positively influenced and demand shopping in Lidl if you ever travel around here (Central Europe) in the future
Regarding the biasing, its the tube I think but dont worry much. The fact you are not able to set bias as intended by the amp designer does not mean the amp is not going to work or is not going to sound great. In fact, some tubes may sound better with somewhat lower or somewhat higher bias from my understanding. The led indicators are just there as a guidance to:
Set roughly the same bias for both channels.
(If possible) set bias roughly equal to what the amp designer considers optimal.
My recommendation: In case you are initially unable to set bias as intended, just use the amp for an hour with the closest to optimal possible bias. After that, try again - you may be more successful this time as the tube settles in. If still not satisfactory, give it another go sometime later. If still no luck, just set bias to be roughly equal for both channels (either somewhat lower or somewhat higher compared to what is indicated as optimal by the diodes). Lower bias may prolong the tube life a bit but may not sound at its best in some cases. Higher bias may decrease the tube life but there is a potential for better sound in some cases compared to lower bias. (You would need to check by ear or, even better, measure the amps' performance.)
Got a text from the customs office saying that the package touched ground but that I'd need to go a bit out of my way to pick the damn thing up at the EMS. Earliest I'll be able to swing by there is... Tuesday.
Sorry if there'll be a delay (including the fact that I'm mini-touring the amp among some friends here). I'm last in line for now though? Don't wanna be an inconvenience. Will be keeping documentation of the amp's location starting with me receiving it.
@JustAnotherRando reminded me that I should be checking in, my bad for forgetting!
Anyway, update. So I didn't get to pick the amp up right away because it was held for inspection in a part of a city (not my own) I'm still not too familiar with. Off to a great start, I know. Anyway, my DAC is off at a friend's place for a demo, so I figured I might as well let other people try the amp ahead of me first.
Long story short, I'll just be getting to hear the amp at the top of next week (weather permitting, typhoons have been pretty bad in the area lately). I'll keep it around for a few days, then finally ship it off to @Scubadude. I really do apologise for the delay, my fault for losing track of stuff >.<
