FOR SALE – Signal Corp Wireless Set No. 19 MK II

1942 WWII US Military Wireless Set No. 19 MK II


very rare mobile communication unit, WW2 era, 1942, sender-receiver with power supply. I also have a canvas cover that I ~think~ goes with it, so you get that also. Unit is large/heavy, estimate 100-lbs. Dimensions approx 27 × 10 × 13.25in.

This unit has the multi-language English / Russian Cyrillic front panel lettering, so that soldiers from either USA/UK or Russia could operate the unit. Very collectible.

Untested, sold AS IS, AS FOUND.

$299 + ship or prefer you pickup.  You can estimate your own shipping costs at 100-lbs, suitably large size box, from my zip 15063 to your zip.


Info from Wikipedia:
“The Wireless Set No. 19 was developed in 1940 by the British War Office’s Signals Experimental Establishment and by Pye Radio. The Pye model was replaced with the MK II model in 1941, and the MK III model in 1942. The sets proved valuable for armoured fighting in the Western Desert.

In 1942, the No. 19 Mk II was produced in Canada by Northern Electric Co., Canadian Marconi Co. and RCA Victor. The British design was improved and interchangeability of components such as the valves, was instituted.[3] A majority of Canadian sets used English/Cyrillic front panel lettering, the result of a Lend-Lease contract to the Soviet Red Army.[4]

Post-war, forward area battle group radio traffic carried by Wireless Set No. 19 nets was progressively migrated to low-band VHF using a more modern generation of radios known as the New Range, later to become known as Larkspur. This employed FM and replaced the No. 19 in this role from 1954. As a result, the No. 19’s VHF ‘B’ section was abandoned and removed when sets were overhauled. The Royal Armoured Corps No. 19 sets were mostly replaced in the mid-1950s with a militarized version of the PYE PTC-202 known as the C12 as an interim measure, which were subsequently replaced with the C13 from 1960.[5] An additional RF amplifier for the No. 19 (Amplifier, RF No. 2) increased the daylight operational range up to about 45 miles (72 km). The experimental Wireless Set No. 19 TH (built for the Dutch Army) featured increased frequency coverage up to 12 MHz.

Post-war, the Canadian No. 19 MK II and III was used in the Swedish and Italian Army.”

Q&A regarding different micromhos scores

Hey Tubesound,

Hoping you can answer a question for me. I have an Amplitrex and a TV-7D/U tube tester.  The Amplitrex tests a 12ax7 as new at 1600GM.  According to your TV7 GM calculator, I believe that should translate to 64 on the TV meter.  However, when I test the same 12ax7 on my TV-7 the meter only hits 42.  Does it sound like my TV7 needs some calibrating or am I missing something? Hope you can help and thanks for the great calculator.


Q&A regarding HP Officejet R-series repair

Q&A regarding HP Officejet R-series repair:


I have your article on “Repairing HP Officejet R-series”.  I used it several years ago; cleaning  the mirror fixed the problem.

I’ve lost flexible use of my hands so I wanted to get someone to do the service (suspect it needs cleaning and new bulb).  Local repair services refuse to work on ink jets.

Do you have a recommendation for help in the south NJ area?

Thanks, Jim


repair broken TP-Link TD-8616 ADSL modem

If you are trying to fix a TP-Link TD-8616 modem, chances are good that this is your problem.

On May 21, 2012, I purchased from Newegg a new TP-Link ADSL TD-8616 DSL modem to replace a very old Westell modem that was supplied by Verizon. At that time, the reviews for this product were overwhelming positive. Less than two years later, this TP-Link modem is already broken, and I see that recent reviews are more up and down.

Simply put, this modem had garbage capacitors, which is a common quality-control manufacturing problem with modern electronics.

Symptoms: for the past several months, connection was erratic, sync erratic, speeds fluctuating. Unable to connect to modem admin via TCP-IP.

Repair was as follows: (more…)
