Attention Dyna and Hafler owners!
You can recycle your original Dyna and Hafler chassis and have modern, high-performance AVA circuits at less than new prices.
Dyna preamp rebuilds
Our Dyna preamp rebuilds include new audio circuits, new power supplies, precision volume and balance controls, the parts for all the boards, high quality hookup wire, and detailed step-by-step assembly manuals.
You get new AVA circuits but you pay less because you do not have to buy a new chassis. Pay for only what you need and you can do it step at a time. The Super Pas Three is available either factory wired or as a do it yourself kit, the Insight+ Pat-5 project is available factory wired only.
The following Dyna preamp rebuilds are available:
Dynakit Stereo 70 vacuum tube power amplifier rebuild
The Dyna St-70 was possibly the most popular vacuum tube amplifier ever made. AVA engineering can take this tired workhorse and turn it into a musical gem. The rebuild is available as either a kit or factory wired.
Dyna and Hafler solid-state Insight+ power amplifier rebuilds
For Dyna and Hafler solid-state amp owners, we install new Insight+ circuits with free repairs!
The original Dyna and Hafler audio circuits are now obsolete and on their last legs. So, we strip the old circuits out, problems and all, saving only the chassis and durable parts. There is no repair charge assuming that the mechanical bits such as the power transformer and chassis hardware are salvageable. If not, we will have to charge extra for their replacement.
We install new Insight+ circuit boards of our original design and new power MOSFET output transistors. We improve the power supply circuits and restore your switches and jacks with DeoxIT D5 cleaner-preservative. Input jacks are replaced with gold-plated ones where applicable. You pay less because you save the cost of a new chassis. Except for chassis and mechanical layout, our solid-state power amp rebuilds are identical to our brand new Insight+ amplifiers. Note that our solid-state power amplifier rebuilds are available factory wired only.
