Usual problem is that the air reservoir isn't big enough for continuous tool use. A lot de; /archives//html/Amps/2005-05/msg00108.html (7,277 bytes)
107. Re: [Amps] Orientation (score: 1): Author: G3rzp@aol.com; Date: Sat, 7 May 2005 06:25:37 EDT; You could try to find someone with a working amp and ask them to try it upright and on its side.

Re: [Amps] Gas Regulator Tubes (score: 1): Author: G3rzp@aol.com; Date: Fri, 20 May 2005 18:17:12 -0400; My understanding is that some of the miniature tubes had a radioactive source in them that had alimited half life. This was to ensure starting under dark conditions. So the actual starting voltage mi; /archives//html/Amps/2005-05/msg00220.html (7,089 bytes)
