Since a few days now the LD I+, a tube/transisitor hybrid is on the market.
Information from the venor is available here: NEW ! LD I+ Tube / transistors mixed Headphone Amp..
Further discussion can be found here
This amp has the unique ability to be used with three distinct tube varieties:
5654
6JI, WE403A/B, M8100, CV4010, EF95, 6AK5
Miniatur-7-Pin-Base RF miniature pentode, 6.3V heater
5654W
6AK5
408A
Miniatur-7-Pin-Base B7G, 20V, 50mA heater
Jan NOS (Phillips)
EF92
CV131, EF91, CV138, M8161
Miniatur-7-Pin-Base B7G, 6.3V heater
6AM6 (EF91)
EF92 (left Mullard, right Phillips)
From what I could see the 5654 and the 408A have the same pin out but different heater voltage and the EF92 has a different pin out to the other two.
I am still waiting for my LD I+, but I already ordered a few tubes:
6J1 stock
EF 95 (6AK5W) Siemens
6Zh1P-EV/6J1P-EV VOSHOD
6028 (408A) Philips ECG
EF 91 Siemens/Mullard
6AM6 CEI
EF 92 (CV 4015) Philips
What other tubes are out there, what tubes do you have and already used, which ones do you like / dislike?
