The stock Kenwood KT-5020 tuner is listed as one of the 10 best tuners ever made, it is also the most affordable one on that list! This one has been upgraded by one of the best “Tuna” techs in the country- Mike Williams at Radio X tuners. It has new caps (Silmic in the output section), new rectifiers, new cryo treated Cardas RCA connectors, cryo treated F connector, it has been damped inside and on the bottom, new IEC power inlet, and the final stage of output has Mundorf Silver/Gold/Oil bypass caps, it sounds fantastic. The cap that holds charge for the memory has been upgraded so it does not lose the memory in a power outage. It has a new digital display but the best mod of all was his “Super Tune” … boy does it pull in the weak stations now!
I have owned most of the tuners in the top 20 on the Tuner Info site and this is the best sounding for under a thousand buck for sure. Blows away the Sansui 717’s, Mitsubishi DA-F20, Kenwood KT-9900, etc in tuning and sound quality (most of those other tuners were heavily modded too).
The physical condition is exceptional as is the performance, $400.00 in Radio X mods alone, I supplied the cryo treated parts which were over $100.00. In the last photo you can see the shielding wall separateing the transformer from the tuner, the new solid core Jupiter power wire (these are additional mods along with the carbor fiber over the transformer), some of the damping, and some of the new caps.Scroll
