Floyd Sense <[EMAIL PROTECTED]> made an utterance to the drakelist gang
----------------------------------------------------------------------
Hi Frank. I'm certainly not an expert on the TR-7, but did buy one on
eBay last year and went through a bit of time and money restoring it to
prime operating condition. The owner of this one seems to have a bit
more knowledge than normal, based on some of his comments, such as
having replaced the display. Seems to me that the PS-75 power supply
(based on info in the PS-75 manual) is barely marginal for running the
TR-7. If you operate only SSB, you might get by but CW operation at
full power out wouldn't be advisable. The PS75 manual warns of
increased ripple and resultant CW signal degradation at a current draw
of more than 15 amps (normally about 75 watts - manual doesn't say input
or output). My TR7 draws around 25-26 amps at full output (around
125-140 watts) on CW. So, guess if it were me I'd factor in the need
to acquire a PS-7 or other supply if you intend to run the TR7 on CW.
Of course, if you intend it for just display purposes you don't have to
be concerned about that.
