Hi there!
If you interested, here is info about some components:
ПФ1П-2 - 465 kHz piezoceramic IF filter with 8,5 kHz bandwidth
7ГЕ2А-К (gray module) - silicon Zenner diode for 1,5V 10mA or so, also you can find selenum ones (7ГЕ2А-С) in older radios
ММТ-13 pobably (green donut-shaped thing with hole in the middle) - thermal compensation resistor for soud amplifier bias network
Thanks for the videos!

ПФ1П is a 465KHz IF ladder filter.

The soviets made good radios.
The tin box is the mixer / first IF, its shielded so it can operate at high gains.
On the front it says 'high selectivity', this is made possible by the light green box, the ceramic filter array.

I love watching Soviet electronics and radios repair and restoration .

It is intetesting topic that see the old device be displayed. I used to own very old radio but no hard to find such things

Также можно добавить, что аналогичная модель приёмника выпускалась под маркой "РОССИЯ".

Для прослушивания коротковолнового диапазона Вы забыли вытянуть телескопическую антенну... 😁😁😁
