Another great restore Don! Enjoying the back catalogue.

Don, on the dent, I use a damp cloth and heat it with a steam iron. This causes the wood to swell filling or at least lessening the dent. Let it dry completely and sand as you normally would.

Nice job.

Well done Don! I think most would have walked away when they saw the extent of the butchering.

Don, in my limited experience with tuning eye tubes, I’ve never seen one close completely. Yours looks like it functioning perfectly !!! I’ve seen where the usual 1 meg resistor is bad and the eye won’t respond at all or very limited. Just saying 🤷🏻‍♂️🤷🏻‍♂️

Great job Ron, nice looking radio. And the sound is also great. I'm a litle jeaulous of your skills and patience. Enjoyed the serie very much.

Supersonic Radio in Bulawayo Rhodesia 1955. Mum at evening classes (shorthand and typing). Day-job was at this radio factory. Assembly-line work tuning cans. What? Yup, she frequency-tuned capacitors at final inspection. On return to London she worked at Cossor Radios but, in the office. Our table-top one in Durban (S.A.) was the Philips BD273U "Philetta" Bakelite Radio (1958). BBC World Service and Springbok Radio with commercial jingles (what's that?) were our delights. Pirate radio from L.M.

Hi Don the Columbus 91 has the problem of very weak 6U5 Magic eye. Which are as rare as hens teeth as you know.

Fabulous series of videos - thank you so much

Hi again Don . Just a quick question is the Victor 3165 any good . Cheers again

HI Don great video series. I have just acquired a columbus 91 from 1950 which is very similar . So your videos will be a great help . cheers

Excellent work Don. You really got a knack with a complete radio restoration!

Such a nice receiver, sensibly designed, well built and properly restored. Be proud of that one!

What a great result Don, the radio looks amazing. That cloth really suits it.

This is one radio 📻 that I REALLY like 👍 in particular. I like how the dial light glows (unless it's your house lighting shining on the case). It's so sad 😞 that they don't build these kinds of radios anymore. You're doing such a GREAT job 👏 with sanding and refinishing this radio 📻. Your friend, Jeff.

Lovely job Don. My wife Donna was impressed by the look of the grill cloth. Still the unsolved mystery of the fireworks show from your IF transformer? Thanks for your video.

Awesome work Don, well done! I think we'll make you an honorary Kiwi for that one! 😂 Interestingly, those IF cans are stamped with the Inductance Specialists logo ('Q') - so they're not original. The factory ones are visually almost identical... I wonder why they were replaced? It's interesting to see one was arcing out - Q gear is normally pretty high quality. And you figured out the AC Jensen cabinetmakers part, which is good - I was going to reply about that, but luckily watched to the end first. To echo the thoughts of several other commenters - you should be proud of this one. It fought you a bit, but you dragged it, kicking and screaming, back to life 🙂

Great restoration, love the detail and the way the wood colours came out.

That was superb work! Congrats and thanks for sharing it.

Hi Don, that is a really nice looking set now. I am also a retired telecom engineer here in the UK and we also used to lace the rack loom wiring back in the day. We block stitched the cables beween the racks. Cable ties saw the end of that practice. Quicker but not as neat. I think i would need a refresher course now as well. They are not simple loops but each is a retaining knot, if the twine gets cut. Dave

Great restore Don, I admire your patience. Love to watch you videos, keep them coming

That was some damn fine knob polishing.

Awesome restoration Don, thoroughly enjoyed the whole series on that radio, enjoy your holiday, Cheers.

Excellent job and a great series! That sparking can and dial string snapping were both rather unwelcome surprises to get right at the end of the project! But, very nice end result!!!

This channel is so neat ❤ What do you do with all your new, old radios? And how many have you brought back to life so far?

Holy crap, what a result! I have to admit, initially I wasn't convinced by the looks of this radio, but now you have restored it, it really looks amazing. Congratulations! I really like that dial glass with the white dots as indicators. And then having bandspread plus a 10 inch speaker... must have been a high end model indeed. Again: amazing job and great video series on this radio.

Nice Job !

That's a very handsome radio which now works as good as it looks. One to be proud of.

What a top series Don, thoroughly enjoyed every episode. I laughed out loud when the dial string broke . . . isn't it always the way ! Full marks for the cabinet, looks superb. I'm not too good with woodwork but will give it a crack soon. Cheers

Great job Don, it looks a treat. I laughed when you said the dial string broke, I know I shouldn't but it's the radio restorers curse 😉 You fixed it quickly. Those Rigol generators are very good, I looked at buying one years ago but they were too expensive. Enjoy your in the near future holiday 🙂

I really enjoyed the whole series on this Columbus radio, Paul and what you did with the cabinet is magnificent! 🤩 All the best from Gene in Tennessee.

Very nice job Don! I don't work on vintage radios much - but the care, attention to detail and authentic effort you bring to these videos is inspirational and informative for my own projects. I'm sure that's true for many others as well. Thank you! -JRH

56:43 - Congratulations, Don. That was precisely the same ARRL handbook that my dad gave to me when I was 11 years old. It is probably the best of that era. No electronics library is complete without it. Your friend has good taste in tech literature. And, yes, there is a copy in my book case to this day. Lastly, my dad's was also named Don. You rock!

Cracking job and very interesting description of you work. Corrosion, this may be something you may like to look at as a solution. [ Electroplating - Easy DIY Nickel, Copper, Zinc Plating ] if you past this into YT you will find some useful information. You can localise plating using a solution of Nickel electrolyte and a conductive brush, this is the same process they use to plate mobile phones with gold and charge ridiculous prices. Nickel electrolyte is so easy to make up from a strip Nickel and should blend in with the plating on the chassis. Best from UK

You made the right choice with the dial cloth. It looks great! Lacing is an almost lost art. I was taught it my former work by a crusty old Navy electronics tech about 35 years ago. Ten inches is indeed a huge speaker for a tabletop radio. I wonder if the Kiwis were compensating for something?

Well done young man. Great series to watch.

She's a beaut, mate. Seeing that page on lacing and tying reminds me of my USAF days, and the same page in T.O. 1-1A-14. That's where I learned how to do it. It seems kind of odd that a NZ radio would be called a Columbus and not a Cook. Ha Ha Cheers, Don.

What a gorgeous set! Really wished I this one in my collection - could sit in a darkened room through the night and just cruise and listen to those stations far beyond 😀 jolly well done 👍 and thank you so very much for sharing this

Don, nice job - again! This one is really nice. How many coats of lacquer did you apply, and did you sand between any coats? I recently restored an old electric guitar, and the final clear coat was a nightmare to get right.

What a great video to watch you are a credit to the channel.

Beautiful restoration Don, well done indeed. The grill cloth is perfect, couldn't match the radio's style any better. I'll admit i was on the edge of my seat when you were deciding on the grill cloth's orientation, hoping you wouldn't go horizontal, you made the right decision in my opinion. Thank's for sharing, have a great day mate.

Thoroughly enjoyed all the episodes of restoration of Columbus. Learnt a lot Don as always. God bless…

Thanks Don, enjoyed the series!

What a beautiful job Don. Chapeau. ✨✨✨

Fantastic restauration & video, thank you Don for showing, the effort and passion put in to this!

The cable tieing at the end was a thing of great beauty.

Another radio overhall well done. Will be looking forward to your next challenge excellent work. Cheers from nz

Very fine restoration, Don! Looks and sounds brand new, and the choice of grille cloth looks great as well. It's interesting that this radio was made in New Zealand and is named "Columbus" I assume after Christopher Columbus, and even has sailing ship motifs on the knobs, and yet Columbus himself never sailed in the Pacific. Was it an American radio originally, perhaps?

Hi Don, good video, your radio looks very nice! did you try placing the lamps in series instead of using the resistor like the print shows? Rich from across the pond 😁

Great restoration Don! That was an expensive Radio at the time, 10 weeks wages for me in 1972
