I am divesting of some tubes that I will no longer use. At least I doubt I will. This is a Philips 5AR4GYA tube, new in yellow Philips box. The tube has a brown base. The bottle is labeled PHILIPS in white print. The construction is identical to 1970’s RTC French production. Inside it has hanging filaments, and a simple getter facing sideways. A large amount of flashing on the bottom of one side. I have photos if anybody is interested. I will let this one go for $100 shipped to US address.
