6GH8, 6BU8, you need a sharp cut-off pentode and medium mu-triode, 7199 is long discontinued...6gh8 is a better sub for this tube. a 12by7, 12bh7 combo will be hard to beat as a replacement...
sayang oweidah, i missed you by one hour at spin today...
i took 4 heatsinks today, will come back for more and the cleartops...
lots of polypropylene caps there too...wish they had a website to browse their products...
