I believe you mean the smaller HS? If so, don't worry they are over specified, meaning that they get just very slightly warm, and are connected to the big top plate for extra heat escape, not at all needed.

As you can see the shunt boards which releases much more heat, have the HS in the correct position.

Why? do you want to experiment? SSHV2 vs CCS+VR?

Well, because I had them laying around to be used, also because I am following the very good implementation from Moglia (thanks also for the help).

The VR tubes don't do any harm, and they look great!!!

Hi Ale,
Well the power supply unit, but already started the job, may be like one to two weeks.
Will keep you posted.
Cheers.

I don't think replacing the 4P1L as a driver is an option - certainly not right now. The LL1660 in 4.5:4 sounds great to me. I don't think this is a problem. My cables can be as short as 15cm (6") so I'm not worried about those.

At the end of the day some Lundahls sound better than others. The LL1660 sounds best to me. The LL1692 or LL1692A has sounded just a fraction more dull to my ears, though quite similar in frequency response. Bass is there. But my LL1692 is gapped for 10mA. My LL1660 is gapped fror 5mA. I could put 7mA through the LL1692 - not sure what that would achieve. I could also try it in 2:1 but I'd be a bit short of gain.

Where I need more gain is in my front end - I'm only getting about 0.5V out of my DAC. If I fixed that up to more like 1 or 2v I'd get better ratios on the transformers.

The LL1692A is a decent transformer. As for the LL1635, it was used in the Amity so it has its fans. It's gapped for 5mA so I don't know what it likes as an input. It saturates at 9mA so should cope with 5mA. Maybe it prefers something more like 3mA. Maybe a 01A.

I don't mean they don't work. I mean my own feelings when I see something similar.

It is sub-conscious reaction, can't do anything about that.

Anyone have inputs to this? Thanks!
