DRC1200 v1.08 is available on the website. This fixes a bug with the REC button not indicating that record is armed. Normally the REC button will light dark red to indicate record is ready, then pressing PLAY will cause the REC button to show in full red when record is active.

It appears THAT Corp has announced the end of life for most of it's line drivers/receivers and VCA parts. Unfortunately, this affects our remaining 500 series products. So, we've stopped building our 500 series products for now, supplies are already out of stock.

Maybe somebody (like Texas Instruments) could pick these parts up and keep them in production, but no idea what the future holds at the moment. It's sad to see these parts go away, they were one of the few companies with lots of parts and designs for audio products. At any rate, thank you THAT Corp for all the great work and parts over the years.

So, we've decided to continue forward with our MM1200 tape machine products only. We will keep some small inventory of products available in this market long as we can, but who knows how long parts used there will be available also.

The MM1200 upgrade products we have in stock are available for direct purchase using major credit cards through our webstore. Contact us directly if you wish to purchase through PayPal or Zelle.

Just finished building and testing four new Super Servo capstan boards. We test these with our capstan motor emulation jig, and a final test in the our MM1200 moving tape. The Super Servo capstan board is a precision engineered design and is the best capstan servo board available for the MM1200. These can also be used in the MM1100 and AG440 tape machines. First come first serve, grab one while you still can. Owners manual and pricing available on our website at rtzaudio.com.

MM1200 Labor Day Weekend Upgrade Sale!
We have three sets of matched 15V/27V and 39V/bias regualtor boards for the MM1200 available now. These will be sold in sets for $825, that's a hundred dollars off the regular price. The 39V/bias board includes our new precision digital master bias oscillator design with custom wound pot core bias transformer - lower master bias signal distortion! The new 15V regulator design is greatly improved with a true linear regulator, not a simple zener clamp regualtor. All boards are tested in our test jig and come preadjusted, but some minor voltage trimming is required on initial installation. We highly recommend recapping and replacing the large screw terminal capacitors in the supply as well. Upgrade your MM1200 power supply to improve system stability, and add many years of life to your tape machine!
