Here you go, Graham. As usual the tubies can't deliver what a few searches
with google turned up almost immediately:

Click on the manual for the RCA BC 7A. However, being stereo, this was not
a product of the 50s but rather one of the late 1960s.

The actual spec on page 4 of the PDF is 68 dB below +18 dbm. IOW, only 50
dB below 0 dB. As bad as that is, I would suspect 50-15 KHz (- 3 dB)
weighting. The corresponding spec for a modern console would be about
twice that, IOW over 100 dB. (!!!!!!!!!!!!!!!!!!).

Moving on to component chassic specs, such as those on page 15 (Figure 11)
we see the sad truth - noise level was -47 dBm, with THD speced at 1% over
a restricted frequency range. A modern component would have noise about -90
dBm, with THD no worse than 0.02%.

As usual, we're getting a humongous load of BS dropped on us. :-(



Are you totally sure about that Arny???? I just checked out the
reference you cited above , the RCA BC-7A, that is the right one isn't
it? Because it is a TRANSISTOR console you idiot, - on Page 2 it says -
6 plug in transistorized amplifiers.

No we know it is YOU who talks BS.

Cheers
