Thanks for the help. It does not have any code on the tube glass near the bottom. You can barely make out the Amperex lettering so I think you both are correct. It tests very strong so maybe it will b .......

I received this 6CA7 tube as part of a bunch I bought from a TV repairman. I know it's a 6CA7 and I think it's a Mullard but beyond that I don't know. I can't read the label and can't find the usua .......

So you are suggesting I try tubes in a circuit that have failed on a tube tester as having a short? Isn't there a chance of circuit damage if I tried a shorted tube at full power? I could see trying a .......

Thanks for all the replies. The seller did offer to take the tubes back but would not reimburse me for any shipping costs relating to the transaction. They were willing to only reimburse me the $5.00 .......

I recently bought 5 old stock 6EJ7 tubes on eBay. Once I received them I tested with a recently calibrated B&K 747B tester. Three of the tubes test BAD at under 40%. One had an obvious short and spark .......

I have had both for over a year. I run the Quad II Forty into Spendor S5/3e speakers with excellent results. Very nice sound. I sold a Van Alstine T7 preamp over the QC-24 because I thought the Quad o .......
