- A fairly simple repair on this one, just needed the have some corrosion removed from one of the battery terminals. Also I used Deoxit D5 to clean all of the controls and switches. In addition I repaired the loose dial plastic face plate with hot melt glue.

We never have such big antennas for AM in radios, made in China for our countries (Russia, Kazakhstan, etc.) Usually it has 5 cm in length, or even less. Because of this the signal is low. You guys are very lucky.
I love old radios ! Thanks for the repair and keep it out of the bin.
Nice little radio! Thanks!
Nice work on this little "blast from the past". Since the owner is using it on just batteries, I'd recommend putting some dielectric grease on all the terminals to help keep the corrosion at bay.
As always a pleasure to watch. Thank you.
Great repair! Thanks
Thank you so much sir 💖
from where you get all the schematics ?
I remember repairing many of those types of radios, some had the cassette decks etc.....30-40 yrs ago they costs 75-125 dollars.
So, they were considered repairable products.....I wouldn't even know if you can buy a radio etc, per sae nowadays.
Nice.
Great stuff as usual. Did I hear George Noory from coast to coast on there somewhere?
Yep you did
The watch switched wrists.
Nice vlog, can you help me my xhdata 808 radio suddenly wont start, uses 18650 battery, on pluggong micro usb charger the lcd lights up for a second and nothing. Also i ve noticed the usb charging area getting hot, pls guide how to fix, thanks!
What is the measured voltage on the 18650 battery? Some units charge the battery and draw from it at the same time. It may be as simple as a bad battery.
@@norcal715 I have already tried a new battery still the same?
One sony make audio ok, but fm&am no function one 18pin ic in rf stage and one 9pin ic for fm also one 18pin ic as pre ampli, no rf function what to check and change please help.!!!
Check all of the power supply voltages to the AM/FM RF/IF circuits first.
Should have tested the A/C operation.
Customer only uses batteries but yes I should have. Thanks
