Sure, no problem. Always have a speaker connected when testing, as tube amps do not like being driven without a load.
When you check the bias supply as I mentioned above, plug in the receiver until you get a stable reading. The bias supply also powers the filaments of the phono preamp tubes and the tubes need to be warmed up 30 seconds or so to get an accurate reading.
