Brief & to the point- they stink, monoband or (worse) tapped bandswitch "models". They may be fine for the occassional SSB QSO without pushing it, but otherwise they do one thing with regularity- the

AFAIK manufacturers rarely specify a maximum frequency of operation. However, it's common to specify a maximum frequency for full power ratings, such as Svetlana has done on their 572B data sheet: ht

I tried a pair of those Chinese ones, ended up selling them off and getting a pair of Taylors from RF Parts. The Chinese ones were junk. I also heard that they aren't not made for horizontal use as i

The "Taylors" that R.F. Parts sells are Chinese. R. F. Parts acquired the Taylor trademark a while back. However, the 572B tubes that Taylor brands with the Taylor trademark are supposedly "special"

You are so clueless. The Svetlana isnt even a close clone to the Cetron or real Taylor. Its quite different internally. The Svetlana says absolutely nothing about derating for 6M but if you can read

I saw a pair of NOS Cetrons on eBay about two weeks ago, they went for about $270 for the pair. I wonder how good they are after sitting on a shelf for 30+ years? I imagine they might be a bit gassy

Hi Mike, That's great. I was questioning the availability of "new" 572Bs that are actually good, and maybe the answer is "there aren't any." I had Cetrons in my old SB-200 and they worked well. I don

Using a 572B in an 811-A socket is hardly a test. The 572B is rated for significantly higher plate voltage and plate dissipation than the 811A. Even the worst of the "572B" tubes should perform sati
