- 10-second warm-up required; audio delayed during tube activation.
- The TUBE-T5C with 1PC pluggable NE5532 op-amp, can be upgraded by dual op-amps like 2134/2604/5532/2068/muse02.

- High voltage inside, please turn the TUBE-T5C off first before replacing the op-amp and the tube, and avoid dropping anything inside.
Customer Reviews
I'm using the t5c to add a taste of tube buffer warmth , which it actually does a very good job of at 180 volts for the tube plate. That's quite high for This sort of device. I did my research. It's also useful because it has multiple RCA inputs and a convenient switcher on the front. I send the signal out to my Douk A5 pro amplifier. I had fun doing some op-amp rolling with both of these devices adding the opa-2134. They really sound good. I like being involved with how my music sounds so in a subjective sense I think the t5c had something nice to my music and if someone wants to disagree that's their business I don't listen to them. And it's beautiful to look at. I would give it an additional star if it had a remote control. I plan to add a Nobsound eq9 analog equalizer very soon, because I realize I like doing that also. I don't enjoy digital equalization that my streaming music device features. It works it may be very accurate, but it's just not as much fun.
