Yes, I do and I don't think it is anything to worry about. For that matter, when I first power up my V, I hear crackling sounds that many have mentioned once again....nothing to worry about.
Off topic but related note:
While playing my V and footswitching between channels, I hear no snap, crackle and pops unless I am switching in 10W mode from any channel to 45 or 90 watt in any other channel. The manual clearly mentions to expect a "pop" when footswitching from 10W to either 45 or 90W power selections between the channels. This is expected and will not harm your amp per the manual.
Personally, I primarily run my V in 10W power for all channels while rehearsing (with no pops) and love the excellent sounds I achieve with each channel. For live situations, I run each channel in either 45W or 90W mode and do not encounter any "popping" while footswitching between channels in either of these power settings. For example, channel 1 at 90W, channel 2 at 45W and channel 3 at 90W......results in seamless switching between channels without "popping". Hope this helps.
