Transformer-coupled tube microphone preamplifier, the RMS5A7 Tubule from Roll Music Systems combines the full-featured convenience of a modern mike preamp module with the rich, satisfying sound of a transformer-coupled, all-tube preamp evocative of the elusive bygone classics.

Ive installed 2x Matched Hammond Mullard 7247 NOS tubes from 1963 and they sound great and vintage-y.
Consecutive serial numbers, I bought them directly from Roll Music Systems.

Basically mint, only used in a smoke-free studio. Im selling them to prioritize other buys.

1000.- for both, 530.- for a single unit.

Can be shipped with PostPac Economy Signature (insured if lost or damaged) for CHF 13.50 for both, CHF 10.50 for a single unit.
I accept bank transfer, and TWINT.
