Pulled the tuner assembly from my Fada 799 chassis to have the tuner detent spring made and riveted by Quality Tuner Repair in TX. I've also started removing the tuner and speaker from my 630TS. The 630's control shafts and speaker were severely damaged in shipping along with its 10BP4. I've managed to fix the vert/horiz hold controls and plan to repeat the same repair on the on/vol/cont control. The bright control will need to be replaced. Here's the area that was hit hardest.

That's one serious case of cone rot on that electrodynamic speaker there John!

Is that a case of Brown rot?

No, Rob, that speaker is a fine example of our own Postal Service at work. More accurately, it's an example of what happens when an eBay seller does a crummy job of packing a device he / she has never attempted to ship before despite having detailed instructions provided by the buyer. This is proof that cutting corners and not following directions is an invitation for Murphy's Law.

On the bright side, the voice and humbucking coils appear to have survived intact, and I understand that this is going to reduce the reconing cost somewhat. Since only the brightness and tuner shafts actually broke, that also makes for a slightly better prognosis than if they'd all snapped. Again, a better job of packing would have prevented this.

I've set the Fada and RCA "twins" aside on an out-of-the-way shelf in the shop ... out of reach of postal workers. All the shipping I've done recently has been handled by private carriers. Jan's son-in-law operates a small shipping company called Tamco Delivery and has access to a Liquid Form packing machine. He can do deliveries for me in the Great Lakes region and can subcontract longer trips. Costs are somewhat higher than UPS or FedEx, but the quality of the service justifies the difference. I still use UPS and FedEx on most long trips, but Tamco will be doing all packaging. For anyone who is interested in Tamco's services, the mobile number is 440-336-3006.

Here's my next PROJECT for 2003 and probably 2004. I've removed all the electronics the cabinet is heading for my cabinet restorer next week, from past experience it should be done around Thanksgiving.

ChuckA,

That set looks rather old. You sure it's worth the cost and effort restoring?

Rob,

You sound just like my wife

This Hallicrafters 505 is looking better.

A paper tag on the chassis identifies it as a T-54 and is dated Sept 15 1948.

Am I correct in assuming the 505 and the T-54 used the same T-54 chassis or maybe someone has done a switcheroo sometime in the past?

here is one of my favorite RCA sets,I have had it awhile,the first pic is the cabinet before,second after,the camera really picks up very minor shades of color,it turned out excellent,this will be my last project for awhile..a long while,( i even have a porthole on e-bay that i lost insterest in..).so i figured i should get the cabinet done before i get carried away on other things.
interesting how the wood on both sides of the front mask is a tad different than the masking,it looks fantastic in real life!!
any suggestions ? notice how someone had installed a tiny speaker in place of the original..? hehe..(NO I didnt do it)

here is after..looks better than the pic shows,i have to put the lettering back on and install the chassis..
ok guys.. one question... i can stuff the original 10bp4 crt back in,
or install a 10fp4 crt,the 10fp4 looks fantastic in this set.. the 10fb4 is n.o.s,even with warranty tag...the 10bp4 test perfect..
what would you do? install the 10fb or 10bp..???
thanks
terry

Hi Terry, I haven't seen you around much, I almost wrote you the other night just to see if you were OK

That 8TS30 looks great!
Personally, I would put the FP4 in it, it's a perfectly legit replacement tube for that set.

Eric

Yet another customer's set (Sparton 5085) ready to be picked up. The backlighting from the window and a cheap camera don't do it justice, but the picture is nice and stable. There were some bad resistors and cold-solder joints along with a broken connection on the flyback. This was a DIY project that went beyond the restorer's level of experience, although he did do some neat work with adequate use of insulating tubing to prevent shorts. Most of the soldering issues were in hard-to-reach areas under the chassis.

Here's my latest score for my personal vintage b/w collection ... another RCA 721TS. This one had received a very nice recapping some time before I bought it along with a NOS 10BP4. Minor adjustments of the Horiz Osc. got this chassis working great. It's all set for my display room where its cabinet is waiting. Picture is courtesy of my 5AXP4 bench test CRT.

Here's a link to one of my current projects,

http://www.myvintagetv.com/decca_1000.htm

It's a Decca 1000 projection set. I've recapped it, and have good B+ from power supply, but no audio or any light on the CRT. The CRT does light up just after I power the set off, so I can assume the CRT is good and I have some HV. This set uses a pair of 6SN7's as CRT protection, if sweep is lost they shut down the CRT so not to burn the screen, could explain the no light problem , but not the no audio. As soon as I get the backlog of customers sets done I'll get back on it.

Hello All,
I've begun restoration on the 16" Porthole TV Combo. I've replaced about 85% of the caps so far. Also 2 open power resistors. The CRT tests slightly weak but still gives a good bright picture. The image is a bit distorted right now as you can see in the photo. Seem to squash up at the top and stretch down below. Any thoughts on what causes this to happen? This is a problem I haven't seen before and am wondering if there is an adjustment for it. I haven't touched the lytics yet. Thanks for any suggestions.

Jim
