Tad 1000's quiet?

Combo has acted like this since I bought them both at the same time. I have a Lyra Clavis dc cart on my Basis Tt with a sound smith ruby retip. As I said it is louder bi passing the 150 but I would still guess turning them all the way would be an impossibility. Do all tube amp owners own a tube tester? I'm guessing it's the only way to know if any are bad? I can list the tube types later this evening if that would help.

He states that it has always been this way and I asked what kind of tubes he has in it because as you said Johnny if HD is using 12au7's that could cause the low gain issue.

Brinmeliss, did you buy these pieces new or used? If you purchased them second hand did you contact the seller and ask if this had been a problem for them?

Bought the 1000s on here and after a lengthy delay seller said he had no issues with amp. Bought the 150 from my uncle in Cali that he used. He did some mods to it. I hate to get him involved because he will want me to send it back so he can tweek it and quite honestly I'm not up for it unless all else fails... Amp have (4)KT 88's..(1) el-34.. (1)WY1...(1)12Ax7 and (1) 6E2 per side

One or two el34's?
