Special Note: While Kevin Deal and Upscale Audio are committed to offering the highest level of customer service, time constraints prevent them from offering individual assistance (by email or telephone) in identifying long lost or vintage tubes. These types of questions should be posted to the rec.audio.tubes newsgroup, where Kevin and others will try to help.
