Title: Replacing small tubes. Post by: WA1GFZ on January 01, 2008, 10:38:55 PM My hands are just too big to install tubes in the V2-CDC audio section.
I foung 1/8 inch rubber vacuum hose fits tightly ofer the glass tip of a 7 pin minature. This allows me to guide it into place then I can push it in. Nice to have a handle on the ones hidden deep inside. Title: Re: Replacing small tubes. Post by: W1ATR on January 02, 2008, 12:20:09 AM I use a spark plug puller I bought at sears for a couple bucks. Looks like a pair of scissors with rubber padding on the end. Just the right size for digging those deep tubes out of the 390 and putting them back.

Designed for miniature tubes, made of steel wire, works like Chinese finger trap. Very effective. Have never seen another like it, so guard it with my life.

No? ;) _-_-WBear2GCR Title: Re: Replacing small tubes. Post by: WA1GFZ on January 04, 2008, 12:09:09 PM good for yanking them out but the hard part is getting it in.......just like everything else in life. (sept for marriage) AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
