JNS Vintage Radios and Tubes aims to be as accurate as possible when describing and testing radios and tubes. However, we are not experts in all Antique/Vintage Radios, Electronic Equipment and Vacuum Tubes. If you see an error, please contact us thru the eBay messaging system so we may correct the listing.

I believe this to be a Mullard gold pin tube from the 1980s although there is no manufacturer branding that I can see. Taken from a working environment and in working condition but I have no means of measuring it.
