Hi Myles,
I an really a novice to this website but I am impressed about the number of people participating and about the pro advice I have received so far. I have here a couple of questions that you probably are one of the most experienced individuals to anwer to:
- I have a Laney LC15 15W tube combo. I play it upside down since I want the tubes to release heat upwards (PCB is on the top (in normal position) and tubes are attached to it. The tubes have clips that hold them in place. When the amp is placed in any position there is a pretty high frequency "sizzling" noice heard from the amp -- difficult to say if it it mechanical and electronical noice. What could be causing this noice? Could it be a symptom of old tubes that need replacement? Or perhaps the holding clips are causing the noise? Are there any ways to isolate the cause? In general, when do you know if tubes need to be replaced?
- Secondly, I also have a Tube Works hybrid combo (tube preamp, solid state power amp)and when I place it on a tilted amp stand its reverb does not funtion at all. In a straight vertical position there are no problems whatsoever. Is it common for amps with spring reverb do this?
Thank you very much for you advice, in advance!
Edit: I place these questions to the general guitar forum too.
