Just curious, rather spend the money on upgrading the amp.


I was going to buy one to try out, but never did get the chance to.

otherwise id let u know :]

Pretty happy with my WA22 now, used to be a speaker guy but the WA22 + HD 800 haven't let me switch on my speakers for couple of weeks now. Maybe next year I will follow you on the Glenn 300B path depending on how favourable your impressions are when you get one :L3000:

Don't get me wrong, the WA22 is a great amp for HD800. I had it for over three years, only selling it to fund the WA5LE. After I aquired the WA5LE, my work is too busy for me to keep it as paper weight. At time point, I have not turn it on for over a month.

Didn't know you had WA5LE, it not in your sign. I thought you were going for Glenn's 300B amp. Is the WA5LE more dynamic / less tubey than the WA22 , does it have better low end slam / extension ?

Have a question , I have this Integrated Tube Speaker Amp.

 

http://www.cayinusa.com/Product_Name.asp?Category=26:56:40&types=1

 

It has 4 KT 88 power tubes, 2 pairs of 12AX7 & 12AU7 - which I guess are the driver / pre-amp tubes & a tube input socket marked as  5AR4, Can any of the rectifier tubes mentioned in the comparison be used in this socket ?

No the 5AR4/GZ34 filament is 2 amps most of these tubes draw 3 amps and you can damage your power transformer.

You can try the 5R4 it draws 2 amps but has a larger voltage drop. Maybe you will like the sound of the amp

running at a lower B+ voltage.

Just tried CV 593 on the WA5, wow!!! 

 

This tube jsut keeps blowing me away, its pretty much just as good as the U52, maybe slightly less nuanced, but everything about it is so good, perfect tonal balance and the bass is really nice.

Is that that one of the 5U4g's that cant be used in the stratus?

I did try the Philips 5R4GY. It cannot mach the superb "Liquid Minty Coolness" tonality (DG trade marked phrase, used with permission :D)   & clarity of the Philips GZ34 Metal Base.

I tried a couple of 5r4 with the grey plastic base and I like them the best for my otl amp.  Better than the gz34 or gz37.   Best of all its still cheap.

Can the 5R4WGB be safely used in the Glenn OTL?

post #314 of 478

Its safe, been using it for a month on it and no problem.  But ask Glenn just in case.  My otl is kinda different but not that much.

post #315 of 478

From list of rec's i own, Glenn had mentioned not to use Sophia  & EML Rec's in his OTL amp. So yes, it will be better to check with him about 5R4WGB also.
