Yeah I know, it's very time consuming. Fun and worth it though.
Tip of the day: 70s Matsushita EL34s, best of both worlds; both the creamy mids of the the Mullard and the woodiness of the Philips.
No, sublte difference: Mullard was acquired by Philips in 1928. Philips & Matsushita started working together around 1953, in 1955 Philips equipment was bought and used (the same year Philips bought Amperex). The Matsushita (long plate) 12AX7 & EL84 tubes up to 1959 are carbon copies of Philips 12AX7s & EL84s for instance (the ones starting with N as factory designation). In the (possibly mid) 60s it is said Mullard knowledge/equipment was used by Matsushita.
Wulf had the 84 magazine and it kind of had to be an EG60-180 given the specs, finish and open zebra pickups (assuming they are stock!). Wish they hadnt had their stickers removed!
As much as I like the Gibson R8 I got, my Bacchus Classic is still the #1 for sustain, tone, and playability. I have some Seth Lovers in there now which I think I may prefer to the stock ones by just a little bit.
