Universal Audio SOLO/610 — single-channel all-tube microphone preamp and DI box. The classic Putnam 610 console circuit in a portable desktop format.

Bought new from Thomann in July 2023 and used only in my home studio, mainly on vocals and acoustic instruments. Fully functional, never repaired or modified, no faults of any kind. All pots and switches are smooth and quiet. Cosmetically excellent — only minor traces of desk use, all shown in the photos. Original tubes, chassis never opened.

Features:

• All-tube signal path (12AX7 + 12AT7), up to 61 dB of gain

• XLR mic input, front-panel Hi-Z DI, Thru jack, switchable mic/line XLR output

• Selectable input impedance — mic 450 Ω / 1.6 kΩ, DI 2.2 MΩ / 50 kΩ

• +48 V phantom power, low-cut filter, phase reverse, ground lift

• Steel chassis, hand-built in the USA

Included: original box and packaging, power cable, and the original Thomann invoice.
