Hi Jim, The good thing about the sweet little GU74B tetrode tube is its stable high gain in grid-driven AB1 configuration with a simple untuned swamped grid input circuit....no messy band switching

It is always good to hear from you Dave. IMO there is nothing wrong with a bit of bantering around especially with self absorbed fools who profess to know so much about amps and tubes but know so

I just wish Dodge would build in more reliability. Carl

I made two posts last night and they have the correct time stamps of 12:18 and 12:28.? However, I went to bed a bit after 4:00 AM and they hadn't shown up here. As I use Charter as my ISP and Mercury

Test #6 to see why a post is not making it. I will delete the name of the tube and see what happens: I have an amplifier tube that has developed a grid short. I have determined the grid short

I take your point that we shouldn't be hurling abuse at each other but do we really need someone like (as Carl described him) King George III watching and judging our comments?? Who watches the

Yeah, but Challengers and Camaros are SO much better than cheesy Ford Mustangs! Ed

Yes, and George's recently publicised set of prescriptive rules and posting guidelines are very befitting and appropriate.. Ham radio interest group forums are intended for friendly exchange of

Used to be post turned up almost immediately, now they take up to hours. This is the third post I've made and nothing has shown up yet. The problem is probably Yahoo's server hosting Ham Amps?.?

As has been said, traffic may be slow, but it's not dead. I notice many of the newsgroups are a bit slow as of late.? Social media? What I? like about Ham Amplifiers is that it isn't moderated, or

I, too, am getting all posts. Maybe someone’s email client needs adjustment.

Im getting yours, Joes, Jims, and others OK BUT I am not using Yahoo; they come thru Outlook Express on an ancient XP machine. Carl

And King George III recenty posted that he will be monitoring AMPS closely and blocking ALL off topic posts! Gee, like so much bandwidth is used on that long obsolete forum. Dont let the door hit you
