2019年10月26日 · I actually picked up some samples prior to the inventory liquidation. My friend didn't have any of the most common left (STK0050, STK0060, STK0070, STK0080, STK0100), but did have a lot of good originals that are great subs. STK1060 for example is a great sub for STK0050. The only difference is the STK1060 has internal emitter resistors.

2020年5月12日 · Hello- New to the vintage receiver sx-780 test/repair arena. Acquired an sx-780 with a shorted Darlington STK0050. Was looking at the replacement stk0050 from this thread- and the parts list/ebay item...

2016年6月18日 · Their has been a bit of interest for a replacement of what was the original Sanyo STK-0050 module used in a SX-780 receiver. Many question the integrity of what can be obtained these days as STK-0050 modules. I decided instead of sending these files to individuals or trying to make a buck from...

2019年6月18日 · Many of them are surprisingly cheap, and of good fidelity...certainly good enough fidelity to equal the STK0050, yes? I bet I could find two power amp modules, and install them, and keep the total price including labor under $200, and the customer will be thrilled to get his Pioneer receiver back in working order.

2006年11月15日 · I had a pioneer SX-780 with one STK0050 and the other an NTE part. I was having problems and switched out the NTE with an orginal STK0050. The NTE was marked with a stick on label which I peeled off and found the original STK0050 part number printed on the part. I stay away from NTE.

2019年4月29日 · Hello. I bought a used STK 0050 module to replace a bad one. I have already done the work to verify that there are no other problems in the SX-780 into which it will be installed (thanks to help from Merlynski). Is there a good way to confirm that it is in good working order, or at least to...

2016年6月18日 · The specific reproduction discussed in this thread is for an STK0050, which has two stages of current amplification, whereas the CR-840 part (or STK0060II or STK0050II) has three stages. I don't know how important that difference is, but I think it is very likely that this thread's device would function electrically, and reliably, in a CR-840.

2018年5月11日 · There is a discreet pcb thread floating around here somewhere. I haven't owned anything that uses them in many years (think 30+)

2021年10月26日 · I've seen this on eBay: STK0050+ Pioneer SX-780 or marantz SR4000 replaces STK0050 STK0030 STK0040. It looks like it replaces the STK0050 in the way the DIY kit does, but doesn't need adjustment. It looks like it replaces the STK0050 in the way the DIY kit does, but doesn't need adjustment.

2024年9月11日 · Can I also use this replacement design (made for stk0050) to replace my STK0029? I found the STK0029 datasheet (file attached) and there I can see that the circuit topology is different, but the general characteristics are the same for both except for the "maximum supply voltage". Maximum supply voltage STK0050: +53/-53 STK0029: +37/-37
