[QUOTE="Nidri, post: 861580, member: 1342"] I know it's expensive but would it not be worthwhile braving the 'Bay to get a fourth GE to complete the quad set? e.g. https://www.ebay.com/itm/One-pair-of-7581A-Tubes-From-GE-Close-Ratings-Different-Getter-Shape/371430926600?hash=item567b022908:g:wk0AAOSwDNdV6vdn Otherwise (heresy!) I've read good things about the new production Tung-Sol 7581[b]A[/b]. (There was an earlier 7581 - supposedly the newer A model is much improved.) https://www.tubedepot.com/products/tung-sol-7581a-new-production-power-vacuum-tube If the Rand wasn't so weak these semi-NOS Winged C's are also really, really good (I only have a pair unfortunately). https://www.watfordvalves.com/product_detail.asp?id=273 Or take a chance on some [i]cheap[/i] NOS Sovteks? https://nesstone.com/product/sovtek-5881-6l6gc-nos-tube/ OR some NOS Philipses: https://www.ebay.com/itm/JAN-Philips-6L6WGB-tube-NOS-matched-quad/292610567088?hash=item4420f2ebb0:g:u2gAAOSw-b9az6TH 2c [/QUOTE]
