Yes, I forgot about Tubemonger. Very reliable dealer. I bought a matched quad of NOS Siemens E84L from him about a year ago and they are still going strong and sounding nice in my 1959 Pilot 402 receiver. I bought a quad of Penta Labs( cherry-picked Shuguang) KT88 tubes from Dougstubes, and not only does he measure and test properly, he labels each tube with the test results, packs them well with free shipping, USPS Priority, and followed up with e-mails to make sure that I was happy with the tubes. Talk about great customer service!
