The 1966 dated coded "C" arrived last week in remarkably clean condition. It had been languishing in some warehouse for years in a military fibreglass transit case, marinating in that amazing military smell :-) There was tiny bit of water in there when I unpacked it but I suspect that got in recently as the counter was pristine. It "sorta" worked on first switch on but now it's much better after a black-beauty-ectomy and a bathtub-plasty (thanks again Brian). The +300 terminal on the plugin connector was bent and just a smidgen away from a disastrous short to one of the other terminals. The manual warns in several places about power supply shorts- they can destroy a large number of Ge diodes. There were some intermittents that responded to deoxit and it's now working very well. I still want to disassemble the crystal oven though, and install a thermal fuse. The C/D models had an improved oscillator compared to the A/B versions. This one has a 1 Mc crystal in the oven rather than a 100 Kc. It feeds a regenerative divider where the 100 Kc output of the divider is multiplied by 9 and mixed with the 1 Mc input to give the 100 Kc output. It's not self starting so there is a neon pulser that kicks the 9 Mc tuned circuit a few times before being locked out by a bias circuit once it gets going. An external standard at either 100 Kc or 1 Mc can be just fed into the mixer and the divider does the rest. Very nifty. Once the crystal oven warmed up the untweaked 10 Mc signal measured 10000.000 on my GPS referenced counter. That's most impressive for a 40 year old machine! I have always liked nixies, but I must say the neon column display is very attractive too and gives you some idea about the regularity of the input signal that you don't see with nixies. That's especially so with the optocoupled nixies that HP used in their counters. They respond quite slowly. What with these 2 counters and the Tek 555 it's like Jurassic Park down here :-) 73, Morris ----- Original Message ----- From: "Jim Hill" To: "Old Tube Radios" Cc: Sent: Sunday, January 14, 2007 3:07 PM Subject: Re: Countersaurus resurrected > Hi Morris: > Nice to hear that someone got his running.

Sometimes the pin is slow to respond due to lack of lubrication and dirt accumulation over time. Couple that with rapid dial excursions and it's bound to happen sooner or later. With the R-4B dial at 500, the PTO frequency should be around 4.955 MHz and the PTO slug should be almost = all the way in with between 1/16 to 1/8 inch left out. At 0 the PTO = frequency should be around 5.455 MHz with 1/2 to 5/8 inch of the slug out.

The 5 cent piece had always been made of nickel. (That's why it's called a "nickel") However, because so much metal was going into the war effort, it was not possible to use nickel that year. Instead they used a mixture of metals (I think it was brass and copper) called "tombac". As well, instead of the familiar Canadian Beaver on the back side, they used a victory torch and "V-for-Victory". "V", of course, is also the Roman numeral for the number "5" as in "5-cent-piece." Here's where it gets interesting. The government was doing everything to encourage people to get involved in the war effort. When the coin was minted, a message in MORSE CODE, was applied to the of the coin. Although difficult to read with the naked eye, but under a strong magnifying glass the message becomes quite clear. It reads: "We Win When We Work Willingly" (each word starting with a "W") I thought you might find it interesting that Morse Code was used on Canadian coinage.
