TAD Tube Set for Hiwatt SSD-504 Custom 50 Signature Series | Various Tube Sets

Our Tubeset for the Hiwatt SSD504 features our outstanding RT-7025 TAD REDBASE 7025/E83CC HIGHGRADE   in the first position (V1) because of its high gain, but low microphony, powerful mids and a round, rich overtone sound - and therefore perfect for the input stage of your preamp.

 

For the second position (V2), we recommend our RT003 12AX7A/ECC83  TAD Premium Selected.  This tube provides for very good gain, tight deep bass, fat mids and a silky top end with overall definition and brightness. It is selected with balanced systems and improves overall response

 

For the third position (V3), our RT003 12AX7A/ECC83 TAD Premium Selected works best. This tube delivers very good gain, tight deep bass, fat mids and a silky top end with overall definition and brightness. It is selected with balanced systems and improves overall response. Best for clean tones, as well as for sounds requiring deep-bass power like any modern preamp.

 

True fatness comes with our RT003 12AX7A/ECC83 TAD Premium Selected in (V4); for the big & warm clean sounds and mellow top-end when pushed to overdrive. Reducing brightness slightly, this tube delivers true midrange-punch.

 

For the power tubes nothing but a matched pair of  RT122 EL34-STR REDBASE TAD Premium Matched are to be used.  The clear and harmonic open top end allows for great clean tone and at the same time the TAD EL34-STR REDBASE offers incredibly powerful mids and equally powerful bass.  Consequently, this EL34 provides a maximum of gain and dynamic response.

 

Idling current should be set to 35-40mA per tube.
