For fellow C3g users: have you noticed a large different in perceived gain/loudness between the Siemens and Lorenz versions of the tube? I feel like the Lorenz has significantly less gain, the difference in loudness at the same volume knob position is feels like at least 5-6dB to me. I have multiple pairs of both brands and they all exhibit this behavior consistently. Considering the electrical specs are the same regardless of brand I find it rather unusual.

They sound different to me but I have experienced this as a difference in frequency response. Siemens sound 'brighter' than genuine Lorenz. Have never thought of gain.

My experience is the same. The Siemens are definitely brighter and thus sound louder, whereas the Lorenz are more subdued. And given that the electrical specs are the same, I too am inclined to think this is due to frequency response. But then this is just a WAG on my part.

It sounds to me like a greater difference than can be explained by only differences in frequency response, but I do think that's probably a component of it. I always feel like I'm being force fed the music whenever I switch from Lorenz to Siemens and there must be something to it.

I don't switch to Siemens much anymore since I prefer Lorenz. I'm not able to analyze the reasons for the difference, just to hear it. Of course the synergy with output tubes is a deciding factor.

There is a GEC Foots Cray tube called 5A/152M that I believe is similar to the C3g but it has a different pin-out. Does anybody have experience with it?

It is not that expensive but I have developed an allergy to more adapters so ATM I don't feel compelled to try it.

For some reason I ended up with some less common tubes as my favorite combination in the GOTL. End game? - Don't know, but meanwhile - YES!

Don't know how old the driver tubes are but guessing from the 40's. I am roughly the same age and I also have some wrinkles lol...
This combo is excellent. Perfect match for my Sennheiser HD250II. The main problem is that once I get into listening I don't want to stop and I go to sleep too late.

WOW looks awesome Mordy!

Stay up too late listening? Noooo, say it isn't so!

I know the feeling! I am late for bed, as I type

Glenn-wanna-be's...there is another Glenn GOTL that is avail for sale.

Send me a PM and I will send you contact info.

Cheers!

Now GET TO BED!!

Okay okay, I am going to sleep - it's 12:12 in the middle of the night...

I think I have a one track mind. When I saw this bottle of seltzer water all I could think of was

Arcturus tubes!

Don't feel sorry for this one...it lived a "good long hard life"

 

[Xcalibur255]

Uh oh, did he go gassy?

 

[whirlwind]

Uh oh, did he go gassy?

Yeah...I had used clear fingernail polish around the base for some time, as it was a bit loose

I think the demise of a TS 5998 deserves at least a moment of silence, just out of respect.

Tonight will be the final time I will see and hear this lovely combo in my home. Gonna listen to the Atrium and then some VC, and maybe throw in some HD250 for old times sake.

Tomorrow I'm packing my GOTL up, and on Monday, it will begin its journey to Hawaii, where its new owner, @robo24 hopefully will enjoy it as much as I have and take good care of it.

So long dear friend!
