I only found 2 of them with stringing info and then that was sketchy as they don't tell you how much is required ...
Don't know if that's as 'sketchy' as you think it is - out of a dozen or so original service manuals for vintage radios I own / have owned, only one specifies the length of the dial cord (it's for an Astor BNS, so Astor collectors may find more). Usually you just have to suck it up and go "ok, so it's
x inches long there,
y inches long there, has 2 turns round a drum that's about
d inches diameter, so I'll need about 2*(x+y) + 2*(pi*d) - plus an inch or so for the couple of turns on the dial knob shaft, and another 6 or so for tying off"
.
Even 3rd-party manuals like the US Beitman's / Rider's / Sam's, European ESdRI, or Australian AORSM, rarely give the overall length. Heck, Sam's put out books that were nothing _but_ dial stringing diagrams, and I don't think cord length is mentioned for any of them...
... so I've ordered 3M of the cord which is more than enough, but at least it will allow to have a second go at should I screw up the first time
A couple of handy tips: There's 2 common dial cord sizes - "Standard" 0.028" (0.71mm), and "Thick" 0.035" (0.89mm). 'Nano-cord' comes in a variety of similar sizes, has similar grip / non-stretch properties (after giving it an initial pull), is usually a pretty good substitute in most cases, and you can buy 100m of the stuff for the price of 3m of proper dial cord...
One thing I have come to realize is that my radio says its a Vega 215 on the fascia but on the inside of the fascia it says B215 and I've also noticed that my LF or audio amplifier and power board is NOT the one depicted in all of the schematics that I have so far come across
I have also located a proper service manual, hopefully its in english and is complete.
For what it's worth the only model numbering on mine is on the back where it's labelled "Selena F8-TR19-B206".
The actual naming of these things seems to be a mish-mash of transliterated/romanised cyrillic script, translated Russian, and abbreviations. As far as I can tell (& leaving out the cyrillic that the forum doesn't handle):
- "Vega" appears to be based on the manufacturer, Minsk Radio Works (Belarus). It seems at some stage, prior to Tento being formed, they exported under the name "Belarus Radio Works", abbreviated to "Bera". The actual cyrillic for that would transliterate into roman script as "bena" - but it you ignore that and treat the English "Bera" as more-or-less Cyrillic Russian, it comes out as "Vega". Which is a more Western-acceptable name anyway...
- "Selena" & "Ocean" are straight translations of the Russian model names.
- "B215" or "B-215" are translations of the Russian for the model number (which would be transliterated/romanised as "b215")
- "Tento" is short for "Technointorg", a Russian export trade group formed in the late 70's / early 80's.
So, sticking to the "manufacturer, brand/line, model number" pattern we usually use in the West, it's probably most correctly a "Vega Selena 215" or "Tento Selena 215" depending on age. But the manual would likely refer to it as a B215 chassis;)
They also seem to have made major running changes during productions, so it doesn't particularly surprise me that a presumably late model (based it being a Tento, not a Vega) like yours varies considerably from the original schematic. If it's just the amp & power board, you'll probably find near-matches for both amongst the later models.
(I will say that most of the above is just my speculation based on "research" (aka Googling
) over the last year or so. I don't read/speak Russian, I've only seen my two B206's and a handful of others, and don't claim any other special knowledge about Russian radio models or manufacturing, so if someone knows better then please correct me!)
