Technics SU-VX700 Amplifier

Rare Stunnin SU-VX700 Amplifier 2nd from Top of the Line In Pristine condition serviced No time wasters please The Technics SU-VX 700 is an integrated audio amplifier from the early nineties. It delivers 2x 90W into 8 Ohms and is specified with a THD of 0.007% (20Hz .. 20kHz, rated power). In my opinion it is one of the better Technics amplifiers. Whereas the sound of an amp is always subjective to a large degree there are some design aspects that are a bit more objective. What I particularly like about the SU-VX 700 is mostly related to its simplicity and repairability: Many other Technics amplifiers use one or two hybrid ICs in the power amp section. With mostly no stock available from reputable sources, a blown hybrid IC is a likely death sentence for an amp. In contrast, the SU-VX 700 uses 2SC3280 (NPN) and 2SA1301 (PNP) bipolar junction output transistors in a TO-3PL package (looking similar to TO−264 and TO-247 transistors). Although it might be difficult to find original Toshiba transistors, it seems like there is an asian brand still producing a transistor with that exact number. However, I would likely try the very similar, but more robust complementary transistors MJL3281A (NPN) and MJL1302A (PNP) made by onsemi. The amp has a very clean layout with three large PCBs and a few small auxiliary boards. It is very easy to work on. (There is a small hatch in the chassis that provides a partial access to the underside of the main board. It might be useful in some cases.) Most connections – in particular those after the capacitor block – are not soldered, but instead use connectors. It doesn’t have the infamous corrosive glue all over the PCBs – might not be old enough. Actually, it seems they didn’t use glue at all. You decide whether that is a good thing. I don’t mind.
