Indeed, so will I!
If it doesn’t work... cry perhaps?
By the way, lifting the 39k does nowt.
And no post this morning. 🙄

Increasing R8314 until it works, having absolutely no clue why that's needed? Doesn't sound good either...
39k? Are you lifting R1309 instead of R8309?
Solved!
You know what? I'm just plain stupid and I sincerely apologise for taking your time away.
The problem was a bad solder... on the fuse PCB (!) at the back, precisely at the big connectors - all the solders were bad in fact!
It led to the -0.7 V missing on pin one.
I'm not exactly a beginner you see, and yet I finally figured what was wrong after 9 odd pages. Forty years of fixing amps and I didn't see that.
Daft, innit? 🙄
I thank you all for your moral support, which was hugely appreciated.
Fancy a spare TA anyone? The old one is still in place.

I so nearly said the other day to 'check the fuses'. Honest 🙂 and was recalling this:
It was like yours, something that got really interesting the more it went on.
Sony TA-3650 power rail resistors burn
A work colleague (one of our best engineers) once nearly gifted me his top of the range Hitachi 3 head cassette deck. It was driving him NUTZ because it went dead whenever he wanted to record something special and yet the fault never showed up when looked at.
In the end the issue was a fuse, the fuse wire was only touching the fuse end cap internally and had never been soldered to the cap.
I'm just pleased its fixed

I knew it was something silly.
Boy this thing sounds good on my big Cabasses... they are 95 dB sensitivity speakers that need a little taming and this does it.
The phonostage is excellent.
I understand its reputation now. Really nice.
Listening to the ubiquitous Big Band Spectacular LP right now. Really really good.

Ta. I must have reflowed dozens of solder joints and replaced about 30 caps in this thing.
All the cerafine caps were... just fine!
The hi-fi tech who took it in for repair finally gave up. He managed to short a driver transistor and forgot many joints (I always inspect with a thread counter).
The two big PSU cans were also in perfect condition.
Amazing!

The LV105 has been on for hours and nothing is too hot. Offset is low at about 3/5 mV.
It seems to work beautifully and, above all, sounds absolutely superb.
Its reputation is fully justified, but it has to be matched to the right speakers.

Pleased to hear its all working well and you are finally getting to enjoy it. Worth the effort 🙂
