RCA CRT expansion bladders needed	Can't Post

Hello, I'm looking for an online source for purchasing replacement expansion bladders for the CRT's in an RCA PTK195 chassis. These are the rubber bubble type held in place with a plastic cover & 4 screws. CRT's are good, but the bladder on the blue gun is leaking. Fortunately a thorough cleaning of the main board got the set back up & running. TIA for any help
Bruce

Are they split or leaking around the edges? If around the edges maybe you could use some type of high heat silicone to seal it.

Thanks, only one is leaking, but it has a pinhole just off center in it. I want to replace all of them if I can get ahlod of some because I am replacing the fluid in all guns. All RCA distributors I have contacted say they are not available, and want to sell me new CRT's IF they are available....Can't see throwing a perfectly good TV in the landfill because of one diaphram with a pinhole in it. Seems dumb to me!!

Since it is only a rubber bladder....maybe you could inprovise and try some type of out of the ordinary fix. Maybe take it to a plumbing shop and look for a similar type of material you you cut down and seal with silicone. I agree it shouldn't be necessary to throw it out. Any repair place will just tell you to replace the whole unit, at least thats what I heard whe nI was asking about replacing my coolant. But I would definitely look for an alternative to the current rubber there.
