Pyrex glass aeriall insulators
Talking of dogbones, I am looking fora couple of those Pyrex glass aerial
insulators of the 1940-1960 era. Not the big ones but the ones about 100 mm long. Anyone got a couple? Alan VK2DRR |

They're too expensive! Use a glass cutter to cut the end off a soda bottle and use the glass loop as your insulator! --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Pic at: http://www.sparkbench.com/xmtr030510-2.jpg Its kind of tacked together as a 'prototype' in the photo. Now that I've got it fairly well tweaked out its time to rebuild it properly and replace the new parts with some OLD parts :) Dropped a large dime at PTOP today. 6AG7 VFO!!!, 42 Buffer/Doubler, 807 PA. 0D3 regulator. Showing about 15 watts out on 40 with a clean enough signal to put on the air. -ex |

Lovely stuff! But what is the cloth in the backgound for? To keep the
valves warm and thus enhance frequency stability? :) "Bill M" wrote in message ... Jeffrey D Angus wrote: Bill M wrote: I've located all the parts I needed. Thanks guys.
