Ha ha, watch your speed Arnold! I hope you are having a wonderful time here in the states.

Right now, you picking to go to L.A. instead of N.Y. this time of year...you are a Genius

Thanks Joe. I was driving quite slow until Glenn and Matt bought all the 5998s.

Ha ha....maybe you should have picked Florida

If those are the 5998 tubes with the domino plates, they have hit the jack pot!

I have never heard the 5998A tubes.

One thing for sure, the tubes will be NOS from this seller.

Glenn, Matt

Any chance you wanted to donate a pair of 5998 to a poor boy like me?

Haven't seen any rectifier pics here in awhile, so figured I should do something about that.



This is an N.V. Ratron AZ12. It was manufactured sometime between 1941 and 1945 in Beek-Ubbergen, Holland, for the German armed forces. It sounds quite similar to the Telefunken AZ12, but the mids are bit more forward and it's usually less expensive.

Again, the AZ12 provides at most 200ma, so it is not mighty enough run the GOTL with a pair of 6AS7G or six 6BL7. However, when used with efficient headphones in a four-6BL7 configuration, the AZ12 is more than adequate. And of course, it is also suitable in the GEL3N. A very nice rectifier.

There is, the 5998A which is more like the 6080 bulb type. @2359glenn are your sure these are the domino plate ST type 5998s (e.g. original Chatham/ Tung Sol 2399/ 5998)? I don't have any interest in buying more at the moment but I thought I should toss out this info.

The ones I bought were domino plate but I don't know what he has now or in the future.
I am not a fan of the 5998 anyway.

Thank you Rectifier King, I'm crazy about rectifier too thanks to you
Let me know if you spot some cheep 45IU tubes. The inflation for this tubes is very high

 

[gibosi]

Yeah, unfortunately 45IU are not at all common on eBay, and worse, the price keeps going up. But for sure, if I come across a good deal, will let you know.

And the rectifier on the right appears to be a British Tungsram FW4-500. Is this yours? And if so, what do you think of it?

 

[jekjek]

Yes it is.
Compared to u52 is less warm. Very clear midrange and less mid bass

It is OK rectifier. But once you have tasted 53KU there is no way back

 

[gibosi]

My impressions are similar. It reminds me of the British Tungsram 6SN7GT....

It gets boring after a while but its very good for movie

 

[whirlwind]

Since we are talking rectifiers. This arrived from Santa today.






Sounds great...really nice imaging and sweet mids.

Glenn, is the voltage drop for this 350 ?

 

[leftside]

Yes it is.

Agreed.
