Members ksl Posted August 10, 2023 Members Share Posted August 10, 2023 G'day.... Has anyone ever seen 6V6's that are this tall (see pic)....? The amp's maker, but not the previous owner, said the amp performed well with them, & they could be Chinese oddballs.... They're totally unmarked, and the one on the far right, is my standard sized Tung-Sol 6V6.... many thanks ॐ💃 Quote Link to comment Share on other sites More sharing options...
Moderators daddymack Posted August 10, 2023 Moderators Share Posted August 10, 2023 You say the amp's maker said they work? So ask the amp maker wtf they are. There are dozens of equivalent tubes for 6V6, some direct substitutes [eg. 7408, VT-107. plus many 'militarized/ruggedized' variations] by many manufacturers in many countries over the decades [they were first introduced in the mid 1930s]. Many are not exact, but may tolerate higher temperatures and/or plate voltages. Since the ones you showed are unmarked, it would be difficult [read: time consuming] to spec out the size of the glass on all the variants from all the manufacturers. If they work, and they fit, what's the problem? Since you already don't know the mfr, you may never find them again. 1 Quote Link to comment Share on other sites More sharing options...
