True Life Audio TSP-1
The TSP-1 is True Life Audio’s True Series tube preamplifier.

What True Life Audio says
True Life Audio describes the TSP-1 as a single-ended triode design loaded by an output transformer, sharing its approach with the Supreme Series SSP-1.
Two separate circuits share one chassis in a dual mono layout. The gain stage uses parallel 12AU7 tubes, and the output transformer is wound by hand to TLA’s own design, continuing the company’s long tradition in audio transformers.
