Sky, two questions.

Do you really ride around on your bike with those Audio Technica's on? :-0

Do you have your home amps posted in order of favorite down?

I don't know if you caught me in the thread about the Bugle Boys but I'm about to pull the trigger on the old MG one way or the other! (i know I know, it is a sickness)

No, my gear is not listen in preference order, exactly...maybe I should...really more in the order I got it in. Kind of a PITA to move them around.

And I don't own a bike

THX, I just can't see myself running around with those AT phones as my portable :-0

Portable could just be moving about the casa so I understand it just looks funny when you call it your portable rig with full sized cans. Heck, I liked your old portable rig with the LaRocca strapped to the Tank:-)

I'm going to wait out a while (and Administrations) to see if the dollar gains any ground before purchasing an Iqube but I'm sure I'll be going there one day too:-( LOL

Skylab... to save me reading through this long thread, what tubes are your favourite in the 337 and where's the best place to buy them?

I like a good solid bottom end (bass head!) with slam & impact without the bass being boomy/flabby and over powering the mids/highs and don't like piercing fatiguing highs.

The RCA JAN 6AS7Gs are pretty good. You could also give the Phillips 6SJ7WGTs a try too.

Yup! That's what I have settled on. RCA JAN-CRC 6AS7G's, and JAN Phillips 6SJ7WGT's. You can easily get the 6SJ7WGT's brand new from Angela Instruments on EBay, $24.95/pair. The RCA - JAN 6AS7G's are a little harder to get - you have to win some on EBay - I don't know anywhere that flat-out sells them, although you could check with Antique Electronics Supply (Antique Electronic Supply).

Don't forget to run them in for a couple of hours or else they hum like crazy.

Yeah, they will eventually become dead quiet, but mine took a good 8 hours before that finally happened.

The 6AS7's go in the front.

I use the same combo and it sounds great.

I have some 6SL7's on the way to try out in front as well.

I've been searching for replacement tubes and have noticed quite a range in prices for the 6AS7G tubes. The cost of a pair is as high as $110

For the tube experts out there, do the the higher priced tubes provide a significant increase in SQ? How much would you recommend to pay for a pair of 6AS7Gs

As with most tube amps, I think replacing the input tube (6SJ7) changes the sound more than the output tube (6AS7).

The most I paid for the input tube was ~$25 for the pair of 6SJ7WGTs. The most I paid for the output tube was ~$50 for a pair of 6528s.

Those are my limits. Yours may vary but I think at prices beyond those two, you'll be hitting extremely limited returns.

Also, I finally made a mod to my 337, it was quick and dirty because I didn't want to solder just yet.



How does it sound? I'm going to let it burn in a little longer before making real conclusions. I'm hoping the better dielectric characteristics of teflon caps (paralleled with the current 51uF MKP Solens) will improve the sound. There's actually no room in the amp to fit these beasts, that's why they're on top.
