$52 per tube

Authentic & Tested. Tubes we sell are ALL tested unless otherwise stated! All tubes are cleaned and well-taken care. Look at the photos for the highly crystal-clear glass and clean pins despite being over half a century old!


*** Please do not trust any tube seller without posting any test information on the tubes, especially vintage ones. Always check and/or request the testing or supplier information of the tubes when buying. Without test information of the tubes, you can never tell how much of the life time of the tubes is left and its condition. How to trust when tube sellers just said 'tested strong', 'works like new' such frivolous comments to certify conditions of the tubes? Worse, some tubes listed did not even come with such comments. Or it could just be a meaningless % percentile reading without context. Although the readings do not absolutely dictate and gaurantee the tubes, it is at least imperative to supply these data for a better peace of mind regardless. ***

FREE shipping with SingPost normal mail. Additional S$2.50 for tracking service.


Rectifier tubes are tested from supplier with TV-7 vintage tube tester. Information of test readings are obtained from them. Typical new rectifier tube values are 50/50, with minimum values at 40/40.

• Tube #1 = 55/56
• Tube #2 = 56/58

For vintage tubes, American tubes offer fantastic performance value for money. The quality these tubes possess is unrivalled compared to today's reissues without costing such a premium like vintage European counterparts.

Rectifier tubes tend to be underrated in amps, but fact is they should not. A good rectifier allows the rest of the power tubes in the amp to perform even more optimally, resulting in better sound more than you can imagine. They do change and improve the sound with great vintage tubes, and for quite significant measures.

274B/GZ34/5AR4/5U4G/5R4 are all interchangeable rectifier tubes.
Sylvania tubes are often sitting in the middle between GE (value) and RCA (performance). I always tell customers to go for Sylvania tubes because they just perform so well for the price. One can never be disappointed with Sylvania tubes as they will upscale the performance of your amp no matter what. I am that confident.

Sylvanias are always about clarity and tight bass. They bring the listening experience to a joy. The top end always sparkle without being harsh and mids/mid bass are so clean and pronounce. These 5U4GBs give a quick attack in bass.


Comes in white box.

All vintage tubes come with 1 month warranty.

What you see is what you get. When we sell tubes we always will take various angles of it so to make sure what you select is exactly what you saw. No substitutions, no dishonest replacements.

Note: unless specifically mentioned, we do not label our out-of-production tubes as NOS (New Old Stocks), a term so commonly branded in many tubes seller. There can almost never be any guarantee these out-of-production tubes are NOS; they were mostly made in the middle of 20th century!! Who tells the tale that they are still new?? No doubt there will still be, but the changes of hands of all these stocks made this verification too difficult. To us, tubes can test excellent or test like new, but we call them all vintage tubes.
