Hello! I've got a Laney LC15R at home, have already done some mods to it previously when the tranny blew - my fault for using a 5A fuse when it said 0.5A or something. In any event, I've already replaced the tubes with recommendations from DougTubes, changed the tranny, and I believe the caps have been replaced as well. I've been reading up, and it appears that this is one amp that is quite popular for modders to work with, so I'm open to suggestions. Here are the changes / mods I've seen: 1) Stand-by switch Q: Is this necessary? Would I derive any tonal benefits? My laney seems to warm up fairly quickly, as I tend to turn the amp on first before playing anyway. 2) Some Penthod / Triode Thing toggle switch Q: what's this? 3) Speaker upgrade I like the way the amp sounds actually, pretty sweet overdrive when the tubes are pushed. However, the amp does sound pretty boxy and so I believe an upgrade here is in order. An option is to buy a 10 inch speaker. However, as I'm concerned about the boxyness so, this may not solve the problem - still 10 inch! The alternative is to get an extension cab with a 12 inch speaker. I see vox has a nice v112 extension cabinet which ain't too pricey, anyone with thoughts about this? And this brings me to my next point... 4) Converting the LC-15R into a head. I'm open to this option, but what does it involve? Would be expensive to house the guts of the amp in an amp head (I suppose I could email Nik from Ceriatone to see if he's got a suitable chassis)? I like the way it sounds when its pushed, so I was thinking of maxing the gain / vol on this amp for a natural amp distortion / overdrive, thus using an amp selector to toggle between this and my JCM2000 for dirty/clean. However, my concern is whether doing this would speed up the tube decay and that of my transformer, if so, how much faster? My other concern is whether a head-version of the LC-15R would be able to power a regular 2x12 Cab (This option may be on the cards, esp if I take this baby out for gigs). 5) Any other mods? I'm not interested in getting another amp - I already have one. But as this is my first tube-amp and I played a couple of memorable (if not bizarre) gigs with this amp, I'd like to keep it. Not to mention the fact that it sounds pretty good to me as it is!
