    Has certainly been a revelation - sooo much better IMO than the 5881’s. Smoother and warmer

    I put in Gold Lions - I think they sound really good

    Has anyone upgraded the transformer in their JTM 45 RI to a Mercury Magnetics? Wondering how much of a difference that makes in the amps tone

    I built a JTM 45 kit and used the Shuguang KT66's it arrived with. Big, fat, and round tone.

    Are those supposed to be good tubes? Never heard of them

    what’s the tranny like in your amp? Vintage specs or more like the one that comes with Marshall’s RI ?

    Weber WOT45HHR : https://www.tedweber.com/wot45/ HHR stands for High Head-room . Not sure if they still offer High and Low Headroom versions of that tranny.

    Are the Shuguang KT66s "good" tubes. They are reliable, but "good" is a matter of personal preference:

    I like the shug kt66s as well. They sound great in my amps that use kt66 tubes. They also have held up. No tube failures.

    I was surprised to see their price yesterday when I looked them up. More than 2x, from what I remember.

    I switched my JTM45 reissue tubes from original to TAD KT66. I love clean tone now. Cranked is different.

    I built a 45 and used Gold Lion's with a Classictone OT. I wouldn't change a thing. Plug in a Strat with a touch of reverb and it's perfect.
