Most people say its the other way around. I have the straight based ones. Bought them for 17€.

Curved is supposed to be rarer and slightly better.

Both seem to have the exact same internals. I found little difference in sound, maybe the curved are slightly warmer, but might just be placebo. Anyways both excellent tubes, i think theyre basicslly the same, just curved looks nicer and probably rarer too

Oh. I thought the curved were the gems.

Is there any difference between 1834s and 6AS7Gs?

Thanks Stavros.

The GECs are perfect in Glenn's OTL with a GZ37.

I haven't rolled the 6SN7 much.

A1834 is just the MOV type code.

A1834/6as7g/cv2523 are the same

Which gz37? The mullard cv378 or the cossor high wycombe version which is supposably better and looks different?

Lovely looking tubes, those.

The cossor and maybe the Brimars are hard to come by now. They appear on ebay once a while and then it usually ends with a high price. My only two gz37 from cossor cost me 110usd each. A steal at today's market.

yeah impossible to find at those prices now, all 300-400+ $

 

also the GEC U52 is pretty expensive and in the same price range.

The Mullard CV378.  I don't think I have paid as much as $200 each ever.  Maybe $150, and that was relatively recent.

post #5726 of 10310

yeah i paid about $100 for mine, a regular mullard cv378 (skinny bottle)

post #5727 of 10310

Yes, just as I thought.  Glenn's OTL definitely improves with a better ac cable.  Just used the Pangea AC-9 from my other amp and the vocals I was referring back as a bit harsh and unrefined has improved.  The hum is also less pronounced.  Cant wait for my AC-9SE cable to arrive.  With close to 20 hours of break-in time it seems things are starting to marinate quite good.

Apologies , the curved are the rare ones.

 

Even more rare are the black based ones.

 

I need to check my stock to see what the differences are structurally.

post #5729 of 10310

Thought mine were Cossor fat glass gz37, now that I tried to find them, there Zearix.  Anyone know if they are a rebrand of the Cossor? 

post #5730 of 10310

Zaerix were traders.

The tubes look like Cossor.
