We agree again Alan. Henry started off great but went down hill fast with
their cut rate parts, mechanical nightmares, shoddy work, etc.

Another comment in my prior post...crossed paths with yours. I suspect
that Dan has no real in depth RF amp experience otherwise he would not
make so many ridiculous claims....sounds like MFJ ad hype.

When I used to live out in LA area we used to take our cars across the
border for cheap rolled and pleated upholstery....they were notorious for
extra holes and poor fits.....maybe sub contract for Henry now ??
