Dec 31, 2008 - Happy 2009 from Ampmonster!!!! Thanks to EVERYONE who has helped make this business a success! I have been working diligently the past year on getting more immediate parts availability. This helps speed up the wait time for service. I have also organized and tested a lot of vintage NOS and used guitar amp tubes that I have stockpiled over the past couple of years or so. This includes tested USED matched pairs of RCA Blackplate and Sylvania 6L6 GBs and GCs. Those are good tubes for those players who want great tone at an affordable price. I even have some NOS GE 5881 pairs and many NOS 12AU7s and 12AT7s for those who are interested. Don't forget, I have a LOT of NOS radio and "oddball" tubes as well. So, if you need something, please ask. I may just have it.
