I am offering my DOGE 300B Single-Ended integrated amplifier for sale. It is in excellent condition and has seen only very limited use.
The amplifier comes fitted with standard 300B output tubes and Russian 6SN7 driver tubes, both of which are included in the asking price. If you are interested in upgrading to premium tubes, I can offer various options at an additional cost.
DOGE has a long history as an OEM manufacturer, producing amplifiers for well-known brands such as LUA and Jolida. They later introduced their own product line, combining excellent craftsmanship with high-quality custom transformer design and outstanding value for money.
This is a beautifully built amplifier featuring:
Pure Class A 300B Single-Ended design
Built-in preamplifier
Remote control
Excellent musicality with the characteristic warmth and transparency of the 300B tube
Delivery is possible in Flensburg or Hamburg for a reasonable additional fee.
Please feel free to contact me if you have any questions or would like additional photos.
This listing sits in a buyer’s market for entry-level 300B integrateds, but the €800 asking price is ambitious, clearly exceeding the 75th percentile of €612 from recent EUR comparables, while the median sits at €481. At €800, this is not a bargain; it’s a premium ask for a used unit, roughly 35% above the median, so buyers should scrutinize condition and included accessories before committing.
The Jolida JD-300B is well-regarded for its musical warmth, clean single-ended triode output, and robust build, offering genuine entry into 300B tube audio at a fraction of the price of high-end rivals. Its upside lies in original-owner condition (if verified), new or well-maintained tubes, and included accessories like the upgrade kit option—making it a worthwhile buy only if the price reflects fair used value, not new-market ambition.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Jolida is a tube-audio brand with roots that go back to 1983, when Mike and Hansen started Jolida Inc. in Maryland as a tube-distribution company. The name became associated with a long-running U.S. hi-fi presence, though the brand’s later history is complicated by different corporate entities and regional ownership changes.
Its best-known products are vacuum-tube and hybrid amplifiers, especially integrated amps and related source components. Over time, Jolida has also been associated with preamps and other classic two-channel gear, but it is not primarily known as a speaker, turntable, headphone, DAC, or cable brand. The company’s identity has stayed closest to affordable tube electronics for music-focused listeners.
In the market, Jolida has generally sat in the mid-priced to upper-mid tier, with a strong following among listeners who want the warmth, character, and hands-on appeal of tubes without moving into true luxury pricing. It has also developed a somewhat cult-like reputation among vintage and value-oriented audiophiles, where musicality and tweakability matter more than brand prestige.
