Brilliant advice on backing the screw out till you feel it drop into the thread again! Thanks for that..

100% on the screw threads! I've been doing that for years; even in sheet metal. So many screwdriver pilots simply do not care. Thank you for all that you show us.

The great thing about those diodes is that they are common and very cheap in cost ....

Been watching a number of your videos now, (especially sub ones) and learning a ton. Have you ever worked on/repaired a Rega (UK) "Vulcan" Subwoofer? Is there a process to hiring you as repair technician? Rega made the Vulcan for a handful of years (collaboration with REL) back in late 90s. It's a stunning sub, (darker cherry wood) and has been a perfect 'smaller' audiophile quality sub for a two channel home theater/music system (all retro 90s British stuff). But, over the recent years it's displayed a couple of common sub issues: hums, thumping, now won't power on and blows fuses (clearly now something is shorting out). In looking at the two PC board amp and crossover, it all "looks" really really simple, but I am NOT skilled with proper diagnosis nor repair. Rega, sadly is known for NEVER repairing older electronics, and NEVER releases schematics either. I would hate to just chuck the sub (inherited from audiophile step dad). Thank you for your time and keep posting great videos!!!

Thank you for the video, it was very helpful. Great tip on the backing up the screw before screwing it in - I have always been doing that. I have a question though - Do all ICF-2010 require this protection diode mod? Also, what would be the behavior of this radio if it was affected by the absence of these protection diodes?

The later models had them installed from the factory. The earlier version had a tech bulletin to add the diodes to protect the FET. Without the diodes with external antenna the FET (301, I think) would be affected by static discharge.

Great videos! What have you found to be a suitable replacement for Q303 2SK152? Thanks!

@JonAhlquist Жыл бұрын

Q303 2SK152 is still available. Just purchase a Sony ICF-2010 repair kit. (KZfaq won't let me post an external link.)

What's the large diode and pink wires attached to the secondary power switch on the IO Board on your radio ?

I see at 7:08 that you have installed a wooden spacer to strengthen the right side of the AA battery connection. Would it help to do the same thing at the left end of the AA battery connection?
