Coincident Frankenstein mk.2 amps

Hi Wu,
Thanks for your impressions especially regarding the EML rectifier 5u4g. I
have thought about it but hesitated due to the cost of them .
We all hear differently as has been said many times. I really admire the
Takatsuki ( that's no secret) but in my system the EML XLS just shines and
competes with the Takatsuki closely. I don't hear the short comings you
point out. I'm happy to have both as well as the AVVT 32b. All three make
beautiful music in my Frankenstein. As far as rectifier tubes are concerned
I've used the Sylvania and RCA and didn't notice a significant difference.
Wu what speakers are you using with your Frankenstein? I've only used the
Synergistic Research Quantum fuses and they are an improvement in the
amplifier. 3 amp slow blow.
Charles,

I wonder if any of you had any problems convincing your significant other that the amplifiers you were about to buy did not sound anything like their name implied?

Am breaking in a wartime Tung Sol 5u4g rectifier tube as we speak to be used with Sylvania 6SN7GT Badboys real soon. Speaking of fuses, anyone try the new Audio Magic Super Fuse? There appears to be several fuse manufacturers vying for the top spot...

Hi Wu,

I tried a few different rectifiers and liked the Tung-Sol 5u4gb and Sylvania 5931 the best. The Sylvania is a beautiful built tube.

The Pvsane hi-fi 300b which came with the amps weren't bad, but the EML 300b XLS tubes are much better. They are more extended in the bass and treble have a organic,lively, open, sound which is very engaging. They don't sound slow to me.
I would love to try the Takasuki tubes some day, but are very expensive.

I changed the fuses to AMR gold fuses which sounded a little more natural. Sorry didn't try the Hi-fi Supremes.

Did anybody try different 6em7 tubes?

Wu, where did you purchase the Takasuki tubes, can you buy them straight from Japan? You can answer on my system page if you like.

I'm very happy with my Franks!

Joe,
I don't believe that the 6em7 offers much in choice availability.
I thought you'd notice more organic sound from the EML as it acquired hours. It has what I'd call natural warmth rather than 'adding' warmth. The KR 300 XLS is definitely warmer but I feel that the EML XLS is the more natural and honest.
