Hi All
I have been given a Q-MAX Q5/10 general coverage receiver.
It covers from 1Mhz to 31Mhz.
Valve line up is, 6BA6 RF, ECC91 MIXER/ OSCILLATOR, 2x EF39 IF, 6H6 DET/ AVC, EF39 BFO, 6SN7 1ST AUDIO/ NOISE LIMITER,EL32 AUDIO, 0B3 VOLTAGE REGULATOR AND 5Y3 RECT.
I have searched the net from info and a schematic to no avail.
There was an article in the NZVRS Bulletin 2018/12 from John R L Walker on this set, but the valve line up is totally different.
His set was a double conversion, but mine is not.
Any help with a schematic would be appreciated.
