Hey all, my rectifier seems to me emitting a high pitched ringing sound (seems to be vibrating?). Is there a way to stop that from happening? Seems to do it louder with the fat 6FD7s.   Also is the 6DN7 upgrade worth looking into?   Cheers!

Thank you!   I'm quite liking how they are sounding :).   Quote:  

Is it normal for the amp to run hotter with the Sylvania Fat Bottle 6FD7s than the stock standard ones?

Has anyone tried the driver tube upgrades for WA6? Any particular reccommended? Or the Drive/Power tube option 2 the one to go with? Cheers! Loving the HD600s out of WA6 :).

Quote:   Exactly what I was looking for, is there a good place to get these from other than ebay (pref a place that offers matching service)? Are these the 6de7's http://www.ebay.com.au/itm/NOS-RCA-10DE7-6DE7-Amplifier-Tube-/360386121813?pt=Vintage_Electronics_R2&hash=item53e8afd055 ...

Since this thread is ginormouse, what tubes would be reccomended starters for the WA6? Looking at trying some tubes that won't break the bank :).

Has there been a comparison between the Woo 6 and the Bottlehead S.E.X.? Looking for something to amp both HD600 and DT1350.

I'll have to agree about the bass it is quite tight indeed.

Quote: I wouldn't go that far to say that the DT1350 are in a different league, certainly they sound good - but so do the ESW9 (I have both). I'd say the ESW9s are more musical sounding out of the two, even though the DT1350 does sound "technically" better.   I can see the the ESW9s...

Quick impressions:   Sound quite nice, neutral sig with a good tight bass and highs. Fit is quite good for small head/ears - I can get the right position quite easy and the clamping isn't too tight, though ESW9s still are the kings comfort wise. They isolate pretty well too.   Much...

Is there a comparison to ESW9s somewhere? Also a comparison to DT250s would be quite nice. Currently on the fence after the let down that the T50p's were.   Cheers.

Dang the new model looks nice, wonder if they can "upgrade" my original version to the new one...

HAHAHAHAHA   This thread is pure GOLD, well done OP!!! HAHAHA :D :D :D

Is it possible to post a photo of the amps insides/guts? :)

Yeah my source is pretty standard 2.25vrms, voltage switch is correct for AUS.   Using the SPL meter with the pot set around 11/12 o'clock it's pushing about 80dB which is pretty different to the impression I've been told with RS2 only getting loud around 3/4 of the pot. The usual volume I...
