Thread-Index: AcFz/1JvvW8dEBVuSeWaX7nZdWnuhAAAL62g From: Karl-Arne.A.Markstrom@telia.se To: rsgb_lf_group@blacksheep.org X-OriginalArrivalTime: 23 Nov 2001 09:35:01.0044 (UTC) FILETIME=[1F81C740:01C17402] Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hello, The TT22 is another 6L6 derived beam tetrode pretty much like the 807, but with higher ratings and 11 mA/V slope, anode dissipation 45 W ICAS and anode voltage 1,25 kV. The TT21 is more common, and differs only by the filament voltage 6,3 V, the TT22 has 12,6 V. The KT88 of audiphile fame is a close relative >From 6 TT22's you should have at least 500 W CW output on 500/2182 kHz if the power supply allows. Take a look at: http://frank.pocnet.net/sheets/126/t/TT21.pdf Hope this helps and 73/ Karl-Arne Markstrom SM0AOM =================== Senior Radio Engineer Maritime Networks Telia Mobile AB Nacka Strand Sweden Phone +46-8-6017171, Mobile phone +46-70-6636575 Fax +46-8-6017959 > -----Ursprungligt meddelande----- > Från: Laken, W.H.P.A. van der (Wil) [SMTP:wil.vanderlaken@organon.com] > Skickat: den 23 november 2001 09:55 > Till: rsgb_lf_group@blacksheep.org > Ämne: LF: T22 - Any info ? > > Hi folks, > > One of the local amateurs detected a MF transmitter on a scrapyard. > It is equipped with 6 T22 tubes from GEC, but we can not find any > details > for that tube. > Any info available somewhere ? > > Wil (PA0BWL) >
