Hi

Just a quick note, I have been asked if i would like 10 + sets of Sony SD-208 tubes and projector carcuses with low hours, but before I get them does any one know what projector makes use SD-208 tubes so maybe I can research them out and advertise.

I think they may be rear projection units / tubes if that makes any differnace, i'm not 100% sure myself as I have not yet seen them but have been told they all use SD-208 tubes.

Would there be any interest in these sets or are they bin fodder ?

Don't want to see good stuff go to landfill if they can be used to bring a unit back to life.

Thanks.

Hello,

I have two Sony RVP 4010 rearprojectors. They use 07msu - thats a nother name for sd-208. They are used in LC setups. I use use HD215 lenses and the stock C-Element for a 3,5 meter wide picture.....

here is a link I found:

Hi

Thanks for the reply

They are indeed RVP-4010 unit, 12 complete in fact, have now seen them in the flesh.

One question, apologies for its dumbness, I have a couple of AC projectors (VPH-1271 and VHP-1000) and the lenses come off easy, if these RVP-4010s are liquid coupled LC unit does it mean I can't take the lens off without liquid going every where or is that contained in the C-element block part ? I know the C-Element is concave so the lens rear end must be convex to fit / match right ??? have not taken an LC design apart yet.

And my other question is looking at the other post you linked in are they (SD-208 / 07-MSU) compatable with an SD-187 ? obviously C-element will have to come off and coolant chamber refitted off dead SD-187, I have a VPH-1040 in for repair with really really burnt tubes so much so that the blue is very dim, tried boosting it but no go.

Have not yet opened up one to look, but from the outside they look like they use all the parts from a Sony VPH-1250/1 or VPH-1270/1 projector, PSU looks the same, DC and E boards visible though cover look the same, the alu housing for the RGB amps ect looks the same, all looks like a 12xx has been adapted into a cube with a grill box cover.

Thanks

Hello,

you can take the lens off, the C-Element is kept in position by an extra mechanism.

No idea if you can swap the tubes. I remember one post here in Germany years ago. He tried to make the tube usable for a 127x and failed. But if you have so many, try if you can try strip down the LC housing in one set. And then also check if the tube pins fit the machine pins(!!!). I am not an expert on electronics, sorry...

How many hours have the RVPs. Are they all 4010 or also 4015? If you have both, please check for differences - i would like to convert my 4010s to 4015s.

These are very good retro machine, and they can be converted to good 12xx front LC machines!

Best regards

....and please let me know with what kind of projector you think they are most related to 1271/70/51/72/52

Those lc tubes can be chanced to ac tubes by chancing tubes hardware, it's quite work though. You need to cut hardware from both tubes and glue ac hardware to new tube using rtv motor silicone.

I wouldn't use turps or gasoline to dissolve hardware silicone with Sony made tubes, because these have front glass cemented to tubes bell and I have found out that this seam is very fragile, even glycol dissolve that white cement and makes it soft and can cause tube to implode!

I guess that 07msu is lc version of 07ms tubes. If so, then those work in every projector that use 7"(5,5") Sony 07ms or sd187 tubes after hardware swapped.
Sony 1000/1030/1031, Barco 400/500/600/700/701 and Ehome ECP series for example.
Just compare face plate size to be sure.

8" Sony 07mp or 07msp have also lc versions (barco used 07mpa/mspa names) these can be used in Sony 125*/127* or Barco 800/801/801s after hardware swap.

Hello Ile,

what needs to be compared if I want to find out if a set of 07msu tubes from one of my working RVP fits my Barco 701. The 701 would be a nice progressive DVD LC machine.....but in the moment the 701 has mint tubes but with no air bubble. So work is needed in any way.

Thanks

...but i forgot to mention:

The RVP if chnged to fronprojection are very nice too. They even scan to ugly looking 128khz!!!! 1080p120....but it looks like it sounds. But far better than any 701, which should be one of the best 07ms tube using CRTs.
