The Paraglow was replaced by the Paramount, as RPMac said below. The Paramount could be built as either a cap-coupled 300B amp, or a direct-coupled 2A3 amp. The 2A3 option was included specifically to continue the Afterglow/Paraglow design history. There were several variants over the years.

Direct coupled power amps like this sound great when properly adjusted. But they are pretty high-maintenance because the stages are so interconnected, and the start-up transient causes some problems with a few tubes - most old stock seemed to handle it, as did the Sovtek we supplied. The last revision of the Paramount addressed the problem (and a few others). The Paramount is also discontinued now, and we no longer have any direct-coupled 2A3 designs.

I can go into more of the history, but it would be better on the Bottlehead forum. This forum has rules to prevent using it as an advertising platform and I fully agree these rules are important and valuable.
