Upgrade your vintage McIntosh MC240 with our premium NOS (New Old Stock) tube sets. Experience the classic sound of your amplifier like never before with carefully selected tubes for optimal performance.
RCA 6L6GC tubes are considered by many audiophiles and musicians to be the gold standard for vintage 6L6s. Known for their warmth and rich tonal character, RCA 6L6GCs produce a smooth, detailed sound that shines in both clean and overdriven settings. They are particularly beloved for their midrange warmth and harmonic richness, making them ideal for guitar amplifiers that need a bit of extra warmth without losing clarity.
GE 6L6GC tubes, while sharing some similarities with RCA, are known for their clarity and tighter response. These tubes have a slightly brighter tonal profile, offering more focused lows and crisp highs without becoming overly harsh. They provide a touch more detail than their RCA counterparts, making them a good choice for musicians who want more articulation and brightness in their sound.
For the warmest, smoothest tone, this set is the top choice for any discerning audiophile who wants a warm, robust sound. The RCA black plate tubes are known for their rich sound and gentle highs, making them the perfect match for vintage tube gear. This combination delivers a warm, lush sound, minimizing shrillness.
Looking for a touch more detail without losing too much warmth? The RCA long gray plate tubes provide a brighter sound with increased clarity while still maintaining that vintage charm. Ideal for those seeking a more detailed soundstage, this set is a great option at a slightly lower price point.
For a more budget-friendly option, GE long plates offer a similar sound profile to the RCA long grey plates but at a reduced cost. Expect slightly less detail compared to the RCA sets, but still a high-quality performance that complements your MC240 beautifully.
All options will sound better than any modern tubes made.

Logos: Vintage tubes have a wide variety of logos printed on them. It is not uncommon to see a Mullard made tube with an RCA or GE logo, or a GE made tube with a Mullard logo. Your tube may come with a logo such are Heath Kit, Baldwin, Fisher, Hammond, Magnavox, Fender, Gibson, Silvertone, etc. but the true manufacturer of that tube will be correct to your order. If you are looking for a specific logo please reach out before purchase.
