When I bought my used F1-X there were some issues. This was about a year ago. I immeditely loved the sound with "Flame Koa" but had some problems. When I turned it on with the power amp on it made weird scratching/huming noises until it warmed up and even after it warmed up the gain level went up and down randomly. However, I have solved these issues and I suspect that other Alembicians will want some suggestions on how to eliminate these problems. There are 3 plugs that are potential problems- both input jacks (1/4) and the output jack for the effect loop. They are a switching type jack and can cause noise/ hum if there is corrosion in the contacts.The way to fix this is to use an appropriate contact cleaner and a small brush. The other issue is cold solder joints in the unit (Dave Houck,I can teach you how to fix this). So I resoldered all of them. The other issue can be the tube. Clean the tube sockets with cleaner like I said before. Take the tube to a checker and make sure it's good. Also check to make sure that ALL of the plugs and switches are tight in the chassis- tighten up the mounts. I'm sure you guys already know this but somebody might benefit from this diatribe- by the way my F1-X works great now! Michael (Flame Koa Essence)

The other thing to mention is exercizing controls. Since they are sealed the only way to clean them is by turning the knobs multiple times. Michael
