In the olden days before the mid 20's recordings were made acoustically with the musicians playing into a large horn with a stylus making a direct-to-disc recording. The recording engineer had to place the musicians in the room according to how loud they played, and those that played louder had to be placed furthest back in the room.

Here is a recreation of such a recording with more modern equipment using a single microphone and a two channel tape recorder. There is also present a foot operated tuba where the player plays guitar at the same time - something that did not exist back then.
Note how the soprano saxophone player steps back and to the side at 1:40 to take a solo and the foot signal when it is time to end.
This jazz style is from 1926.

Neat audio recording with no electronics at all. And it played pack the same way.
Electronics came in in the near future.
In 1920 KDKA started broadcasting. To play music the hole band came to the radio station and played around
a single microphone.

So for now,im safe,but if that changes I'll give you a call. You have a spare bedroom? :)
All you gotta do is some soldering chores for Glenn... Just in case, prepare a "Will solder for clean bed" sign :wink:

Congrats on the decision! DAC is critical.

Yep! Massive difference,however as I mentioned in my video I did,the differences werent as noticeable thru my nearfield system as it was thru my Glenn.
With the nearfield I could hear a difference,but it wasnt night and day. Thru the Glenn +Verite,I found myself listening to songs I generally loathe,just cuz it sounded so phenomenal.

How about a 304TL based amp? :)

http://amberwaveaudio.com/the304TL.htm

http://silvercore.de/de/amps/silvercore-audimax/

The 304TL is a 300 watt general purpose triode made by
paralleling four 75TL tubes in one envelope. The TLs or VT-129 tubes
were used extensively in WWII as pulse modulators in the SCR-268 radar
sets and as amplifiers in other equipment.
My guess is that if you have to ask how much these amps cost, you can't afford them...
The third listing - a German amp, costs around $41,000........

Which brings me to another question: A few decades ago I bought a high end integrated amp 100W for around $1,000.00. I just saw a Yamaha receiver now with similar specs for $129.00.
Does anybody have a recommendation for a good sounding contemporary very inexpensive integrated amp or receiver, 100W stable down to 2 ohm, that has separate preamp in? I want to use it as a power amp with the GOTL and I am worried about how long my 35 year plus amp is going to hold up in the long run - a rebuild is way too expensive.
It appears to me that microprocessor controlled amps have brought the price down substantially compared to old Hi Fi stuff.

If I may ask,what amp do you currently own?
Where I live,where everything is silly expensive,getting my vintage gear worked on is usually less than $150.00

Hi Monsterzero,
I have a Tandberg 3006A 150W power amp:

Also have a matching preamplifier 3008A, but only one channel works - could be a bad solder joint somewhere. It seems to me that it would be cheaper to buy a used one (if you can find one) than to have it repaired.
I also have a 1980's Sony 110W integrated AV amp that I like, but it cuts out all the time on one channel.
This old gear is great, but unfortunately I don't know if it worth the money to have these pieces repaired.
If you have information on a good reasonably priced repair place, please PM me.

More adapters from Deyan! Dual 6J5 to 6SN7 and the ubiquitous EL3N to C3g.

In the GOTL, the 6J5 adapter will be nearly flush with the chassis, my amp needs a 6SN7 to 12AU7 adapter on the bottom. Really like the minimalist look of the enclosure Deyan uses for this adapter.

For the benefit of the those very few here who are interested in rolling 4-volt rectifiers....

2019-07-12 22.45.42.jpg

After rolling through the Cossor 53KU, Mazda UU8 and Mullard FW4/500 in search of the best sound from the Loewe Opta EL11 and 5998, I have settled on the Mullard FW4/500. Typically, the EL11 and EL3N have a strong bass emphasis, and the Cossor and Mazda also have a strong bass emphasis, and the end result was a bit too heavy with those rectifiers. With the Mullard, the bass is tighter, with better detail, and to my ears this is the best of the three.

2019-07-16 08.48.31.jpg

This FW4/500 was likely manufactured in the early 1940's and can provide 250ma at 500 volts, so it was a fairly strong rectifier for its time. While less common, Mullard also swapped out the 4-volt heater for a 5-volt one, installed an octal base and labeled it as a 5U4G. I find the FW4/500 to be very similar to the later "skinny bottle" GZ37 manufactured by Mullard, but to my ears, this older tube is a bit better.

This might be a long shot,and off topic,but I need to ask.

Anyone in this thread familiar with Sonore or SoTM network products?
Ive been doing pretty intensive research and have read glowing reports of both. The obvious differences in SQ! seems to be a lush,organic sound from SoTM vs. more analytical sound from Sonore.
I prefer warm,musical but with the GOTL+tube DAC+ZMF headphones,im wondering if the more transparent sounding Sonore is the way to go.

Anyone?
