Well, what kind of valves are they? Someone here might have some they could lend you...

Second, it'd be no harm to take out the valves and clean the pins, and then put them in and out a few times to clean the valve sockets a bit.

If not I've a couple of pre's you could borrow for a bit - DIY'ed music angel, Yaqin MS-12 and a DIY'ed NAC 62. What is your current pre? I also have a few valves floating around. I'm in D4.

There are varied reviews of the AQ2004 - seems a not very well executed design. However, if it is still running the original Chinese tubes then it is definitely worth trying some better ones.

I work at Citi in the IFSC, and can arrange to take one of my pre-amps in to the office with me. Do you need line level only? Probably best to try the Music Angel - it was pretty good to start with for the price (£85 on eBay), but then really improved when I did some DIY on it with PSU changes, better quality components and rewiring with a proper star earth scheme.
