Update  Time owned: more than 12 months
After 4 years of owning this rig I thougth it's time for an update. I have been using the 222-1 regularly. During this time 3 6v lamps have been replaced. Two from the main and bandspread dial respectively and the pilot lamp in the power supply. Other than that the radio has worked flawlesly. It has great audio and the selectivity options work like a charm. I specially like the multifunction switch that measures voltages in the different stages. The crystal filter works as it should and is excellent in crowded conditions. Tuning is quick and smooth and the radio is still well calibrated. I use it with a long wire for which it is designed. Overall it is a great radio.
unfortunately the spare tubes and manual never arrived. The seller at the e place never complied to my requests and became sarcastic about it. So I found the russian equivalents.

Preliminary to operation  Time owned: 0 to 3 months
I have recently obtained one of these although pre-owned. This one came with a manual that is totally Chinese. Hopefully i will find someone who can translate it for me into something i can understand. The purpose of this review is to list the tube compatibility that is shown in the manual and a brief overview of the radio as i understand it.

Apparently from what i can see in the manual there are 12 tubes shown as G1 thru G12.
G1 and G2 are 6K7.
G4, G5, G6 and G7 are 6K4
G3 is a 6U1
G8 is a 6H2
G9 is a 6J1
G10 is a 6F2
G11 is a 6P1

The manual i have also has a nice set of schematics so if someone is in need of this information i will be happy to make a copy for them for my cost. All text is Chinese (of course) with the exception of numbers. The only place i see the model number is in the back of the book where it shows 222-1, 12306 which is the SN and on another line "C, maybe Rev C?

Voltages don't seem to be that odd. One of the oddest is a -40V one. Otherwise plate voltages are +150 and +250 with filaments being 6.3 V. There is one voltage marked on the chart that shows 6.8 (-40v) that i don't understand. It is not connected to the -40V side of the supply in anyway unless it is in the radio itslf. Input voltage ranges from 180 thru 240 AC selectable with a switch on the front of the power supply. The receiver does have bandswitching capabilities and operates between 1.5 Mc and 30 Mc.

I have not powered the radio up as yet because i don't have a step-up transformer for the 120 to 200V AC range required for primary power. While ther power supply has a line cord coming out the back of it for plugging into 220Vac, there is also a shielded cable coming from the back of the receiver next to what appears to be a headphone jack with 5 wires in it. Two red, two green and a white. I'm not able to determine from the manual what this cable does.
