A slightly different version has 5Y3 rectifier and HAMMARLUND HQ100A in big letters on front panel. Hammarlund used a 5y3 rectifier in the early run and at the tail end switched over to the solid state rectifier as Hammarlund was using at the same time in the Hq 170a's & the Hq 180a's. Those with the solid state are Very rare.
