I ended up not getting the Elekit TU-8500 preamp. I contacted Elekit, asking them for specs on the phono portion (specifically the capacitance). They responded by asking why I needed to know, and that they wouldn't disclose the specs for the phono portion. I told them my cartridge required a capacitance of 150-300pF and I was interested in purchasing the TU-8500, but would not if I didn't know the capacitance. They would only tell me that the TU-8500 would not be recommended for any cartridge with those requirements. I was some what disappointed by the whole email exchange. I ended up buying a Pro-Ject Tube Box S phono preamp, and it has 12AX7 tubes to roll!!! I will pick it up when I get off work in 10 days.
I sent the Hickok 533A to Roger Kennedy for a Refurb/Calibration, as the power tubes were reading OK, but any 9 pin tube would read really high.
