![]() ![]() I am building this page on the road somewhere in western Pennsylvania. There are also one or two more new boards planned for 2019……stay tuned! ![]() There is already a new board in stock, but full web site ready build instructions are not ready yet: The progress of the new TSE-II can be followed on the Tubelab forum here: I already have a prototype board running, but I expect that it will be 4 to 6 weeks before the design is fully tested and new boards are in stock. More filtering has been added to the filament regulator circuit to handle 2A3’s without issue. The new board will be slightly bigger to handle 300B tubes, and provide more space around the heat sinks. In the process a list of requests from prior builders was collected and is being accommodated. The TSE is being redesigned to use a different regulator chip. The filament regulator chip used in the TSE is no longer made….in fact Sharp is no longer alive, it is now part of the Foxconn empire. Several hundred amps have been built, but all good things must come to an end…….only to be replaced by BETTER things. It has been an old faithful for 14 years. There are ZERO in stock, and none will be reordered. The TSE board shown in this web site is NO LONGER available. ![]()
