The CT-810, the older and lesser sibling of the CT-1010, is apparently not as good a tuner as the CT-800. Our contributor Marc reports that the CT-810 is less sensitive than his top tuners but is easy to modify for better sound quality: "Stock, the sound is not bad but it is not high definition. I bypassed the volume control, replaced the power supply diodes with Schottkys and changed the lytic caps at the output with polypropylenes. These simple mods gave surprising results. The sound quality blows away a lot of tuners. The front-end first stage is made with a FET. The output stage is made with transistors, which is probably why the CT-810 has a relaxed, natural sound." Our contributor John H. says his CT-810 has "fairly nice and warm bass and good overall range. After removing the 300-Ohm balun and replacing the third filter with a narrower (110 kHz) filter, the sensitivity comes much closer to my T-85 and the selectivity is also improved. The stock filters were Taiyos, and when I replaced them with newer ones I got a jump in signal strength, so they must have had pretty high insertion loss or were out of spec." |
