A LOT OF 4 NOS 811A RF TRIODE OUTPUT TUBES (CH) FOR HAM RADIO, TECHS.  As tested on a calibrated TV-7D/U as follows: #1- 52, #-25, #3- 48, #4- 53 where minimum is 36.  My 30L-1 used 4 of these for years because I operated them within the stated, normal characteristics.  The buyer of my 30L-1 continued to use them and was well satisfied.  FOR U.S. SALE ONLY.   Shipping in lower 48 states (AK,HI higher) via: USPS-GRD ADV--$15.50;  PRIORITY--$20.05.  These units carry my normal 30 day guarantee for refund IF returned with my initials still on the tubes AND units still test as indicated above.  I do not charge hidden, handling, or packing fees unless noted.  I do combine on shipping when possible.  Check back often for more tubes, radios, manuals, or parts.  If bidding on more than one item, do not pay on listing you win individually as I will send a single invoice.  Thanks for stopping by, 73, Joe
