I know that you must be scared to try the amp again, but troubleshooting is easy on SE amps. If you think that your speakers are in danger(very unlikely with 2 watts)try a different pair, less costly.
Swapping the tubes from one side to the other, one tube type at a time, might clear this question up, quickly. If swapping the 45s brings the noise(or silence, now) to the other channel, voila, it's that tube that was now tried in the known good channel.
Likewise, swapping each stages' 417A, you might find the culprit.
This is before you dive underneath and check voltages. This way, you can simply call the tech and, hopefully, only need a tube.
If you want to try troubleshooting voltages, let us know. Resistances must be checked with the unit off...
