It could be any cheap production batch they were able to buy, this is only a reseller that labelled tubes, no own production site. Egro never was a tube manufacturer. Like RSD they bought second quality tubes that were declined for first choice by other companies. They sold the rejected tubes that no major brand would like to sell. Thats why they are always cheap and low quality tubes.
