Renovation of repro walls
September 8, 2017After many years of trouble-free use, I had to resort to refurbishing the speakers because the bass speaker went out while testing a repaired amp and a vintage electric guitar.
Original article reprobeden production.
I tried to get the same speakers, but the Czech manufacturer Tesla Valašské Meziříčí later company TVM Acoustics s.r.o., has already closed down under strange circumstances. Therefore, I eventually purchased other suitable speakers.
