I do not have the carrycase, but bought the battery NOS a few years back, altough never used them. IMHO this is a very good amp to demonstrate the STAX sound if you have to bring your phones.

Dear Forum, I have a quad set of NOS EL34 tubes for sale that I had bought from eBay a few years ago. They were bought for my Dynaco ST70 that I've sold recently, so I do not need them anymore. The original German seller listed these as a matching set, but I do not have the equipment to verify...

Since then, I managed to get a NOS battery pack for 133$ with box. I think this is still a very decent mobile amp!

Dear Forum,   I've acquired a set of SR-5 earspeakers. I am aware that there are different versions available (New, Gold etc.) and I am asking that how can one's determine which version is which? Mine is white (now it's rather yellow due to it's age), and the tag boards are rather silver than...

I use this circuit as a power amplifier

I had the opportunity to test the SRD6SB. I think it has a performance that is highly competitive compared to my SRM-XPro

In my opinion, those are that ceramic capacitors those hold that charge until they discharge by leaking or something. 

Thank you for your help!
