Funny, I tried them twice with the WA6/RS1i and both times I found them to have too much overall bass for me with the S/P-274B. So the first time I bought/returned them to Woo. The second time I bought the adapters from Woo and the the RCA 6EM7/6EA7 Test NOS Dual Triode Black Plates Coin Base Wright Apollo Tubes from eBay and tried them with the Mullard 5V4G/GZ32 and thought they would match nicely being the GZ32 was a thinner sounding than the S/P-274B, but found the same thing…so I returned the adapters to Woo and got a pair of 6FD7 (big bottle's). I paid close to $45.00 (with shipping) for the 6EM7's from a Canadian dealer… right now I have them on eBay for the 3rd time trying to sell them for $20.00, being I can't use them at all without the adapters. I just re-listed them, if nobody buys them again, if you want them I will give them to you at your shipping cost. I hate having things laying around that will never be used when someone else can use them. They have about 2-3hrs on them. If you really want them, being you are a fellow Head-Fier, I will end the BIN and give them too you!
