I may not have noticed it until now since I don't fiddle with the volume alot, but there seems to be crackling on the left channel of my wa22 as I turn the volume knob up and down one step.  Any ideas as to what may be the cause?   Thanks in advance.

Looking to buy Wonder, WBT or Cardas solder in NYC asap. Please recommend a store that carries them in Manhattan?   Thanks in advance,   Y.

A while ago I got my HE-5 stock cable reterminated with a 4 pin XLR plug. Listening through my wa22 I notice a very apparent drop in bass depth, weight and overall snap. Could the cable termination be responsible for this?   Thanks in advance.

Thanks. Got a reply with directions for sending them to a Queens (NY) adress for replacement.   Quote:

After hearing some occasional crackling and lower volume in the left earpiece noticed that the cable terminal is loose. Tried tightening it but I an see the "rod" rotating behind the metal grill. Has anyone else encountered this and is there any way to tighten it? (The metal grill doesn't look...

I take it back. I was listening to some SKA and the snap/sizzle of the sovtek fitted the music to a tee. Moving to some jazz I found the sovtek underwhelming (and thats an understatement) I'm going to try a JAN RCA 5r4GY and a Tung Sol 5U4G while I save up for the EML. =)

One thing I've got to say if you are shopping ebay for 6SN7s is that don't let your enthusiasm get the best of you. I got a whole collection of second grade tubes, that I will probably never listen to again, because I was too anxious to buy. Watch the market for a month or so before purchasing -...

On a side note - I went back to the stock Sovtek rectifier and have to admit that I like it a lot more than the NU 5U4G. Much more dynamic presentation. The NU is a bit tooby for me: loose bass and rolled-off highs. I can't spring for the EML 5U4G mesh yet - any other rectifiers worth...

From my experience with a VAC PA80/80 (a push-pull tube amp with manual bias adjustment) under/over biased tubes sound perceptably worse than optimally biased ones. The amp designer indicated that the 5998 would be up to 40% underbiased in the wa22 circuit. If, however, as Seamaster has...

I just had an interesting conversation with a tube amp designer. Looking at the pictures of the WA22 internals he commented that the WA22 is optimized for the 6AS7 and is severely underbiased for the 5998/7236. Which sort of matches my observations after switching to 5998 - the sound got...

A favor from the people that have opened their WA22 - what is the rating of the cathode bias resistor? (they are the big gold ones attached to the chassis). Thanks in advance.

Is it possible to damage headphones by leaving them in direct or even indirect sunlight? (Just thinking about where to set up the equipment rack). Thanks in advance.

After balancing my HE-5s I can report that while the quality of bass has increased, its quantity and impact have decreased. I've been going through all my tubes again trying to restore the impact - without much success ... Best combo so far are 5998 + Tung-Sol GT. Saving up for an EML...
