STV-X+ — Replaces STV-2H, STV-3H, STV-4H
Well, it’s been a while since I’ve introduced a new part and here it is, AND the revision is done. Our STV-X+ replaces the Sanken STV series of “Silicon Temperature Compensating Diodes”. Not a Varactor diode, I’ll explain the difference later, and hope a picture is worth a thousand words. I was working on an SX-1010 the other day and needed the STV-3H. I had two in stock, but I realized I should make some. My part is four diodes in series with solder pads. Each solder pad you bridge, you are shorting out one junction. You can choose to have 0, 1, 2, 3, or 4 junctions. So three different part numbers can be replaced with my single part. Four, if you need a wire with a mounting hole in it. I did tests and each junction is just like a 1N4148. The forward drop is a bit higher than the Sanken version, but that is what the bias pot is for. I carefully matched the physical dimensions best I could, including the U shaped mounting hole. As for the VARACTOR diode confusion: The SC-15 and SC-20 SILICON VARACTOR DIODES are voltage variable capacitors mainly used in electronic tuners. The STV-3H and STV-4H SILICON TEMPERATURE COMPENSATING DIODES are for stabilizing bias in amplifiers. In the Sanken Databook they are on the same page. There is at least one photo of a Marantz parts bag perpetuating this error.

STK0059+ Output IC Replaces STK0029, STK0039, STK0049, STK0059
While the pictures and video show two (2) modules, but please note this module is listed for individual sale. Our STK0059+ replaces the entire family of STK00[x]9 parts. Compact design, with the same mounting holes as the original Sanken. Just six solder connections. Typical current gain 8,000-20,000 vs original 2500. 15 amp, 160 volt transistors INSTEAD of the original 5 amp, 100 volt part. These same power transistors are used in the 140 watt per channel Marantz SR8012, Denon AVR-X7200W, and the Yamaha RX-A3070. NO bias adjustment, preset during testing. NO paste needed, we supply silpads. NO drilling or grinding to fit. NOT 35 years old or counterfeit. YES, every module tested with our Technics SA-300 amplifier PCB YES, gold-plated PCB. PCB Finish, ENIG (Gold), compliant with IPC-4552. YES, 4 ohm speakers. We use 15 amp outputs vs original Sanyo 5 amp devices YES, free USPS shipping in the USA. Hand tools and simple solder skills required. Technical knowledge required. No returns and limited support, this is not for beginners. We do supply instructions and helpful test tips.
