Although subject to the usual pin 1 problems and grounding, house trailers sometimes suffer from a problem with the aluminum siding being unbonded and ungrounded. Roger Halstead (K8RI and ARRL 40 yea

The tubes for the old Alpha amps cost a fortune. Generally to retube one costs more than the amp is worth. I have a 76A. That's how I know. <:-)) 8874s are *expensive* I'm not familiar with the AL12

The ones in mine are over 20 years old and still give full output. I'd expect a very long life from them, unlike the PL172s which have glass to metal seals and tend to get gassy with lack of use. Rog

I have a TH-5, but I don't know which model. I don't think it's the MKII so it's probably the DX. I'll look for the manual tonight to find out. 73 Roger Halstead (K8RI and ARRL 40 year Life Member) N

Another reason for doing this is drainage. The top of the concrete should be "crowned" so any water tends to run off. http://www.rogerhalstead.com/ham_files/tower14.htm shows a good "crowned" concre

They make abrasive blades for both power hand saws (generally called Skil) and for chop saws. Both work very well on rebar. Yes, rebar gets red hot when cut with an abrasive blade as well. Roger Hals

Use a guide which prevents it from "kicking back", but I don't like abrasive blades on my good table saw. That's the nice thing about a chop saw. It clamps the bar in place and you just lean on it. I

Although still in use today I think you will find they are "left over's" and really are antique. I haven't hear of them being manufactured in a very long time. Still, there may be some, some where.

It depends on how you install them. Leave a "tail" instead of cutting the tie flush. It's not quite as neat, but works well. Make the tail long enough and you can loop it under the bundle. Nearly all
