Know what you mean about the "incisive tone" of 6BL/BX7's...faster/sharper/more dynamic.

Spot on JV.

GEC B36 brown base or Sylvania 6sn7w metal base? I've to toss a coin on that one.

2 very different sonic presentation. 6sn7w is fast, dynamic, precise and ultra revealing. Wide stage and good bass impact. GEC B36 is on the romantic side of the spectrum. It's not overly warm and lush. Not to my ears. It's a great tone. So soothing and smooth.

I've to thank Stavros once again for the GEC B36. It's NOS and came in a pristine GEC box. Can't believe he sold me this jewel.

Some years ago when I used 5U4 rectifier in 300B amps. It was powering two 300Bs and two C3gs that add up to 200ma
at twice the voltage used in the OTL 425 volt or 850 PIV. Someone put in a GZ32 and it violently exploded on the inside.
I only recommend using this tube in the EL3N amp.

Too bad. Matt, do you wanna to try it on your new toy?

This new Scar Jo will protected and loved. There will be no violent explosions. No thank you. This is why I chose the safe option - hexfred.

That will generate spikes when u turn on the amp. and shorten the life span of your valuable tubes too. So just leave your amp on all the time. LOL

A 5U4 is almost instant on almost as fast as SS

You need a period of adjusting to the much different sonic signatures when going from T1 to LCD-3. That said, you might be more a 'details' person just like me. Prior to getting Glenn OTL, my fav headphone is the ZMF Eikon but now HD800 has reclaimed pole position. I'm a firm believer that when evaluating a gear, you need to consider the whole setup. Source, amp, headphone and tubes. To a lessor degree headphone cable. Let's not talk about fuse. You have to find the right balance of romantic and dynamic in the whole chain.

However what surprise me is that LCD-2f is gaining favour with me again.[/QUOTE]
Hi UT,

I agree completely - you need much more time with a new item to fully appreciate it - I just noted my initial impressions.
The total system plays a major role. In my present set up I prefer the HD650 over the T1. The HD650 is less detailed but has a beautiful, warm presentation; the T1 is much more detailed and analytic.
To me it is the difference between a laser photo and an impressionist painting:
(You can count the trees....)

And this soft focus beautiful landscape:

That's why I asked Matt to just run the amp 24x7.

Or use a indirectly heated tube.

I like on the OTL amps with the PY500/42EC4 rectifier tubes , that one will lite up a bit before the other then the second one starts to light...

The 42EC4 worms up nice and slow. I would prefer using the 42EC4 but no tube rolling not cool.
And I ran out of the nice NOS plate caps from my TV store in the 80s
and the dam things cost me $1 can't beat that.

And I thought it was Lake Moraine...
But you are right - checked some old pictures of mine.

You could probably well be right. The hamlet called Lake Louise (very close to the lake also called Lake Louise) is about 14km from the lake called Lake Moraine. Close enough Both are beautiful.

sample some drivers on GOTL. Power tubes are 6 x 6BX7.

These are the top contenders for best drivers from my collection:-

Siemens C3G (more microphonic than the others)
Sylvania 6sn7w metal base
Tung Sol 6F8G black round plates
Mullard ECC31
GEC B36
Marconi B36 metal base

Wondering if you still have/tried your Mazda 6N7G's and didn't you have some 6A6's at one time?
