  1. Hi Terry, The remote (Yellow) terminal on your ME25 is not a remote volume control. This terminal provides a 15V to 18V signal when the ME25 is switched on. This signal is used to turn on a matching ME power Amplifier or compatible power amplifier. Ron.
  2. Hi Jim, sorry for the late reply but it has been a busy weekend. I work for Winovate and specialize in the servicing of ME Amplifiers and pre amplifiers. Currently I am being pimped out to work for an associate, a former Winovate person, and due to Covid19 restrictions earlier this year and the passing of my Mother on the 18th of April, I have quite a backlog of work to do at Winovate. That said, I may still be able to guide you in checking the bias etc on your ME200. Ron.
  3. In a Power Amplifier, it is not uncommon to have +/-50/70/90V power supply rails, But we are talking pre-amplifiers here which would typically operate from +/- 15 to +/-24V rails and rarely need to output more than 3 volts.
  4. Why 5W ? As a 4.7K 0.5W resistor will handle 48V, and no pre-amplifier will put out that sort of voltage.
  5. I recently purchased an A3148 HDMI Transmitter over IP and two A3149 Receivers. All are PoE equiped and also included plug-packs if PoE is not available, from Altronics. Here is a brief overview: "Converts a HDMI signal into a H.264 encoded stream (maximum 1080p @ 60Hz) and sends it over Cat5e/6 cable using internet protocol (IP) over a distance of 120 metres. The advantage of this method is a reduced network load without sacrificing signal quality. It also allows for data to be streamed over Wi-Fi. These transmitters and receivers are very flexible, allowing for various s
  6. 100% agree with what Art Vanderlay said, with one addition to the original question: If you look at the biasing arrangement it is between both output transistor stages, so it affects both equally.
  7. Hi, I have a large stock of KSA1220AYS and its complement KSC2690AYS in Melbourne. Great very linear transistors.
  8. Hi All, Winovate has moved to 17 Metcalf Drive Dandenong South, 9792 1509, some years ago and while I am also working part time in Mentone I am still servicing ME amplifiers at Dandenong South. I Hope that clears things up. Ron.
