My experience with Jasmine aka Darkvoice shipper was exceptional! The item shipped in a timely manner and was at my door in about 6 days. The stock 337 is an amazing amp! It is dual mono with two volume pots (really helpful) and has an incredible amount of headroom and power (and the tubes are downright cheap compared to the ridiculous prices NOS fetches these days). I completely agree with SkyLab's assessment of the best tubes (RCA JAN 6AS7G/TungSol 5998 for power and JAN Phillips 6SJ7WGT for drivers). Aside from the annoying "buzzing" of the drivers - took 24-48 hours for mine to completely become quiet) I have no complaints about this amp. If it happens to develop problems, I have a handy Stereo Service (who specializes in vacuum tube equipment - I know because my Cary 300SEI was in "twice" for repair while I owned it). The 337 is much better to my ears than any other head amp I've owned (and I've had a few). It meets my very simply method of upgrading - do I still think about of an upgrade after living with the piece for awhile? If not, then I'm done! I think this amp represents an incredible value and I would have never found out about if not for this forum - thanks to all!
