We have been using Wako Technical's SR-4N as the basis for the BRi-Audio distribution, but we have almost run out of it in a year or so.
SR-4N is already hard to find, and even if it were available, it would be expensive and raise the overall distribution price.

We have decided to use HMX-Ag from Kojima Solder Mfg. as another solder with similar performance at a similar price.

This solder is comparable in sound to SR-4N and is easy to melt and use.

We will switch to HMX-Ag solder for the next distribution.
