First part have many good comments, and I don't like to make people wait. So part 2!!!!
I will start with...
My first cassete player. Made in 1977. It was able to be good enough cassette recorder, but it had problems with motor controller circuit, i tried to fix it, but all tries was completely unsucsesfull. (it had nonusual motor which was needs in separate controller circuit) Now I made vintage styled bluetooth speaker from it.
One of most famous and popular portable cassette players in USSR. My made in 1984. After years it have many problems too, because some parts are was almost destroyed by time.
Silvano KC-3010 (made in Japan)
Just rare Japanese tape recorder with a radio, about which there is almost no information on the network. Mine was produced in 1977 (the second of my 3 cassette recorders from 1977). To be honest, its quality was quite low, because apart from high-quality components, the assembly was approximately at the level of low-class Soviet counterparts.
Very simple portable radio. That is all what i can say about it.
Spidola 230-1 (208)
It can be usual 1970's radio, but mine is almost unique. This is the one of 100 factory hybrids of spidola 208 and spidola 230-1, they was made as prototypes and have schematics from 208 but in 230-1 body and have unique top panel.
Dad's amplifier, it have some modernisations from original and sounds at level of some audiophile amps from well known manufacturers.
Musical instruments (synths and electric guitars)
Soviet analog strings machine, almost clone of crumar orchestrator in body style of crumar performer (If you interested what is "crumar" you can google it). Mine TOM 1501 was made in 1985.
It work well, with it you can play almost all, of course is you will use some effects and plugins because original sound can be a bit poor for solos.
Solaris aka estradin 314.
Short keyboard analog electric organ. Sounds really good, but you need to use transpose for play bass, because keyboard have only 4 octaves.
Gibson ES styled semi-acoustic gutar, but with plastic body. Was made in late 70's. This model was called worst soviet guitar by many experts, but sometimes it sounds good for some tracks.
Ural 650 custom by D&R
My triumph: most famous soviet electric guitar, but comletely restaurated and customized by me at home. After all customizations it sounds very good, much better than original and some customs. It was present for my friend to his birthday, but in plans making
These all look so cool. I love vintage soviet stuff.
New hobby unlocked: I gotta check these out!
Those guitars are so cool, and I was wrong. My dad lived in Russia in the 1990s.
electronica 302 looks pretty sexy this is a very cool collection holy shit!!!
Also I forgot to add cassette recorder
