Dropped some Mullard branded Siemens nos ‘70s E86C tubes in the Bustard this morning. The original RFT E86C tubes sounded fine, but it was probably just time. Some Tung-Sol 12AX7s in there now, too. Sounding forward, punchy and sweet👍 #thermionicculture#littlebustard#nostubes#santafe

The culprit! Replaced this Electro Harmonix 12BH7A with a NOS Sylvania and my beloved @retroinstrumentsinc 176 is back in form!
