Luxkit A1020 need help!!!

[huytienluu]

Hi
I am using Luxkit A1020 with 4 of Nec 6a-r8 but I tried many time to buy another 6ar8 tube for my reserve.
Unfortunately if my tube is going to die what will I can do with the rest OPT ....remaining thing in my amplifier

What tube can I replace 6ar8 in the future or how can I modify it with Lux OY 14 OPT with 5K

Thanks in advance

Rgds,
Huy

Hi. I have an A-1020 in a good condition. There is no direct replacement for 6RA8. Some of my friends use A2293, but I do not know the details (bias setting, etc.). Also, 6CW5 triode connection may be used, though you have to be careful for the low screen grid voltage specs.

Good luck.

Thks again,

Hi, sure I can share the schematic. However, I cannot send you an E-mail through this board due to your preference setting. Give me your E-mail address.
Regards.

Thanks, but really need to complete a detailed scheme and better assembly manual

Good luck, try writing to Lux.

Could in the event, re-wire tube sockets and use EL84 which is a similar type tube....

Not the right one....

The correct tube is 6R-A8 and is a 15W Japanese Triode only made by NEC, seldom found outside Japan except in sold/exported equipment.
Closest thing would be a Triode wired EL84 and the set adapted to suit, ....

Hi,

Luxman also had valves made solely for them as well.
Most of these were for the local market though some seem to have "escaped" somehow....

Best way is to try to figure out what the closest possible equivalent could and then adapt the design to that. If at all possible.

Best,

Try Monarchy Audio; they were the Luxkit importers to the US in the '80's.
