We selected CELM 0.47uF/400V film capacitors in coupling between 6SJ7 and 6L6. Cathode capacitors are Philips BC 100uF/100VDC. The caps make sound of the amp transparent and detailed.

The shipping of the amplifier (GW 14KG) from Hong Kong to USA costs around USD180 via Speedpost.
The voltage of this amplifier is 220V.

Thanks.

We can re-make this 6L6 amplifier in the similar circuit, the new price is USD530 as the cost of the most parts like transformers had increased, and USD290 is our very special sales price.

Cheers.

Hi Alejandro,

Yes, you can change those Chinese tubes with some NOS tubes:
6P3P can be directly changed to 6L6, 6L6GC or 5881
6J8P can be directly changed to 6SJ7 in glass or metal cover
For the recitifier, can use 5Z4P, 5U4G, U52, 5R4G, 5AR4, GZ34, 5Y3......

Thanks.
Tony.
