Eurotubes, Inc.

What Eurotubes, Inc. does

Eurotubes, Inc. is a privately held, founder-led vacuum tube retailer and distributor founded in 1988 by Bob Pletka and headquartered in Milwaukie, Oregon. The company is the official US importer for JJ Electronic (Slovakia) and also distributes Emission Labs (Czech Republic) and new-old-stock (NOS) tubes, with a catalog of approximately 793 SKUs spanning preamp tubes (12AX7/ECC83 family), power tubes (6L6GC, EL34, KT88, 6550, 5881, EL84), rectifier tubes (5AR4/GZ34), proprietary branded equipment (Pro One Bias Probe, EuroDamper rings), and supporting components (capacitors, cables, socket savers). Its flagship product line is "Retube™" — registered trademark kits that bundle matched tubes tailored to specific amplifier models from brands including Fender, Marshall, Mesa Boogie, VOX, Orange, Peavey, Bogner, Soldano, and McIntosh, serving guitar amplifier owners, bass amplifier owners, and HiFi audio enthusiasts.

The company's technical differentiation is concentrated in its in-house testing protocol: every tube undergoes a 24-hour factory burn-in followed by Eurotubes' own hand inspection, noise-floor analysis via a custom analyzer, Amplitrex AT1000 or ROE tester screening, and — for power tubes — real-time manual quad matching swept from turn-on knee to maximum dissipation. The company maintains 25-30 distinct grades of power tubes to support precise matching and ships with a six-month minimum warranty. This is hardware-level analog measurement expertise rather than software-driven quality control.

Commercially, Eurotubes operates as a direct-to-consumer e-commerce business (eurotubes.com) complemented by phone-based sales support (M-F, 9am-5pm Pacific) and customer consultation. There are no disclosed wholesale, retail, or distributor channels, and no external investors or funding rounds. Marketing is content-led (extensive technical blog, FAQ, Facebook presence since 2011) and SEO-driven. The company employs 1-10 people, and revenue is not publicly disclosed.

Partnerships

One partnership is on record.

• JJ ElectroniccoreChannel Partner/ Reseller/ Distributor · 1 January 1987Eurotubes was founded in 1987 when Bob Pletka became the official US importer for JJ Electronic tubes. After discovering tubes from Czechoslovakia with superior sonics and performance compared to Chinese and Russian alternatives, Bob traveled to Prague and arranged an import partnership with Jan Jurcho's tube operation in Čadca, Slovakia. Eurotubes was the first company to import tubes into the US with the official JJ Electronic logo on the tube and factory packaging.
