Can you provide links to these two tube choices. Thanks
The Telefunken's I got off of eBay I believe, maybe AudioMart. There are a few good re-branded Telefunken smooth plates you can find, and are usually a good deal as they are not stamped with the Telefunken logo on the glass. The Brimar's I got off of Audiomart by a private seller, but were origiianlly sold by Upscale Audio, and sold in their original boxes.
