The filament voltage on my TR-4C is just under 6V at the tube filament pin.
The Drake AC-4 is wired for 120/240V, but the Line Voltage in New Zealand is
230V.
Hence, I presume, this is the reason for lower filament voltage, and probably
lower HV on the plates.
I suppose this means lower electron
Have now purchased and installed two new crystals, one at 32 pf and one at 20
pf, both were recommendations by crystal mfrs.
Neither crystal would work in the circuit but John Kriner was kind snuff to

The MC4316 would also work, it is the full temperature range device if you
can find it. The MC4016 is similar in function to the 74160 TTL IC but only
the power and ground pins are the same.
I looked through my IC stuff as I have a lot of the older types but don't
have any MC4016 decade count
I have for sale a complete, collectible quality B-Line -- R4B, T4XB,
Speaker, PS and interconnecting cables. The R4B cabinet has two small dings in
the top near the front that were rather in-artfully repaired using paint that
doesn't quite match. They could easily be repaired with a little pa
The 16 pin MC4016 ( MC4316/4016 ) is a programable divide by N counter. Not
sure why Motorola used the 4016 number twice, very confusing.

No, it is the 16 dip plastic package.Even the china references are
saying they do not have any!
