I have speakers all re done, small speaker coil rewound, both speaker cones , both transformers, repaint speaker frames and bell's , now maybe next weekend I can fire this old radio up. Dick is replacing the plate choke coil this week , I have two more electrolytic caps to replace also, then Dick will slowly power up and check everything, im sure there will be something not right, it always happens. Stay tuned.

Wow - what an inspirational journey! Just awesome work! Thanks for sharing. That much work would take me months of work and wouldn't look anywhere near as nice.

If you're willing to share, I'd appreciate some additional details concerning rewinding speaker coils. This is something that I would not feel comfortable taking on until I learned more.

Thanks for the complements, the speaker field coil for the small speaker was rewound but I did not do that, I sent it out for that job.

Finally got my baby Strat finished and playing. This 12a58 looks great and the sound is just as nice. Lots of work went into this radio, cabinet and the chassis needed major repairs . These 12a58,s just aren't easy to come across and was well worth restoring . As you can see the chassis has a lot of news parts, just a whole lotta work.

Stunning, just stunning Fred!! I'm always just wowed by the quality and detail you put into your work.

One question about the chassis. I see the candohm resistor wasn't replaced. I've always replaced them with terminal strips and discrete resistors to avoid the possibility of a future chassis short or element going open. Am I just being paranoid?

No, you are not. It is a high failure component and many here replace the whole thing also.

I don't know why my electrical tech didn't recommend it be replaced, I do see one new big block resistor on that strip. I'm not an expert in that field. Mike did install an inline fuse where the power cord is soldered in. Also I had Mike add an input jack on the rear of chassis so one can play a CD player or anything else. One of my other guys Dick Morgan that works on my radios also only replaces those resistors only if there bad, I will have to ask those guys why they don't replace them if there,s a hazard to the safety of the radio . Thank,s for brining that to my attention and thank you for the complements on my refinishing and restore on the cabinet.

Fred does some for himself, and some for other people, hopefully at a reasonable profit. One deserves to be properly compensated for their work.

Absolutely LOVE your work Fred! I've been a fan for the last 5 yrs. I've kind of studied your technique thru your pictures and love it.
I do have a question though. You use Timbermate grain filler as I do now but I have found that some other stains are not accepted by the Timbermate filler like I would want them to be accepted. For instance, on restoring a 40-180 Philco and using Timbermate and then using Minwax Golden Oak wiping stain, the Minwax didn't get absorbed by the grain filler and I have white streaks in the wood. I'm wondering if you or anyone else has had this problem. I know you prefer Mohawk stain, which I love their toner but is their stain more compatible with Timbermate grain filler than Minwax stain and why? I do know one thing, I don't like the white streaks after staining and toning.
Any advice would be greatly appreciated.

Thank You

Dick

Sorry I don't know why the timber mate will not absorb the minwax stain. I don't like that stuff like you said, the white streaks sounds like because the stain did not soak into the grain filler the grain filler remained white in the pores of the wood making that appearance, now unless you sealed the grain filler first then used the stain that would cause your problem also , grain filler has to be stained first and then you apply your clear sealer. Hope that helps you.

No I didn't seal after the grain filling . I just sanded and then wipe stained with the Minwax stain. Yes, I don't understand why the white streaks won't accept the stain either. I just wanted to know if you had ever encountered this problem and if you have a fix for it.
So I think I might try a little more toner in those areas, although I'm afraid it might make it too dark. But it is always fixable. Thank you for responding Fred, I appreciate it.

Thanks Dick
