It’s “Whammer” Time!

Just a quick update to all that has been happening at CTA (Classic Tube Audio)  The shop is full up with a back-log of service work and some of my favorite types, McIntosh and Marantz. Many upgrades are at hand for these beauties. We have been hard at it developing and now in full production and sales of our famous 2A3 tube single ended amplifiers (now 4 models shipping)

All this and we will be heading to the big Axpona Audio Show in Chicago the week of April 9th-15th. Our top line Truth amplifier and our new DAA-3 (Damn Awesome Amplifier) will be featured, all playing nice with Pure Audio Project speakers and Verastarr cables.

Our Whammedyne website is fully revised and a new format check it out at;

later this summer we will undertake a full revision on this website too!, The shop will be expanding with Dr. Tube building out a production build area for all the new Whammy amps (I need space!)

Stay “True to the Tube”

Feedback (The good kind ) !

Thanks for the great work on the Fisher 400cx2.  It has brought new definition to the Zu Definitions IV.  Following the power supply rebuild, ground scheme improvements, recapping with Super Caps, and flawless build of the Gold Point attenuator/power switch this is one of the finest vintage preamps I have ever heard.  I try to shy away from the audiophile adjectives because I have a hard time finding much meaning in them, but this baby is musical with explicit definition.  Midrange expression is phenomenal and nothing is lost at the extremes.  I would put it up against just about anything (within reason of course) and am confident it could hold its own, particularly the phono stage.  Great job, money well spent.


I really enjoy improving the performance of the classics
