  1. Yeah. Yeah. Wishful thinking on my part. However, there are rumors...
  2. Lots of places to get tubes. My latest tube purchase was made at Amp Head because the prices were the same as anywhere else and it was convenient because I was ordering a dual bias probe. Here's the link: http://www.amp-head.com. The tubestore is a good place to go: http://thetubestore.com/ and I'm sure other folks will chime in with where they buy tubes. As far as your reverb goes, for now treat that as a symptom or a secondary problem. The loss in output power would be my first concern. For a first step, unplug the footswitch and turn on the amp. Once it's warmed up play it and see if the reverb is working or not. The default setting with the footswitch unpluged seems to be reverb ON. While you're at it note the volume level. Does it seem normal or is it still reduced? If it is normal chances are the switching circuit has problems. If it is reduced use the front panel switch to change to the gain channel. If the gain channel sounds normally loud the problem is probably a preamp tube. If the gain channel volume is also reduced I would change the power tubes. The bias on a Bugera is weird set up. You can find the Bugera procedure here: http://www.bugera-amps.com/EN/Support/index.aspx The instructions at the link above are for Bugeras other amps, NOT the v22. However, the procedure is the same. The reading you want to get to on your multimeter will be in the negative range (-) of around 15 - 17.5V. Do your own due diligence here. Since Bugera has published no numbers for the EL84 and their biasing circuit and I have no Bugera Service Manual (if such a beast exists) all can and am telling you is from the info I've scrounged up at other forums. Personally, I bias mine at -17.5V. For my particular amp this has produced very good results. Others have posted lower settings and they are happy with their results. So your mileage may definitely vary here. If you do NOT feel confident doing this yourself then do not do it. Take your amp to a tech or get it to an authorized Bugera service center. The extra cost is worth it so you don't hose the amp or worse, fry yourself. If your reverb problem still remains you will, unfortunately, have to have a tech deal with this. Bugera USA is NOT very helpful in getting replacement parts or service information to customers. If you instead choose to consider your amp, as suggested, "disposable", you can dispose of it in my direction. I would love to have a 3rd Bugera to experiment with at my leisure.
  3. Hey Omar! This is a problem I haven't heard before on a V22. I have some questions: Did you have the footswitch plugged in? Have you had the tubes replaced since you bought the amp? Chances are that it is a tube at least as far as the loss of volume. The reverb is digital reverb with it's own little daughter pcb. The only problem I've heard of with the reverb is a "helicopter" or "motorboat" sound. This is typically the fault of a capacitor. If it is the tubes you can change the tubes yourself. It's very easy. No special tools or skills are required. Setting the bias is also very easy but requires a multimeter and an RCA cable is handy but not necessary. A set of ALL new tubes might cost about $90 depending on where you buy them and what brand(s) you get. JJ tubes sound really great in a V22.
