When you're shopping for transformer voltage regulation, the core decision in a tube amp is usually how much specification you want versus how much you want to spend. The Antek AS-1T250 and the Vintage 760 VCT represent those two directions.
Quick verdict
The Antek AS-1T250 is the more documented choice: it is from Antek Inc, has the AS-1T250 part number, and its secondary layout is explicitly described. The Vintage 760 VCT is the lower-priced option, though its brand is listed as Unknown and its condition as Unspecified. The listed price spread is USD 16.01.
Comparison table
| Product | Listed Price | Price Bar | Notable Attributes |
|---|---|---|---|
| Antek AS-1T250 | USD 56.00 | New, toroidal, 250V x2 + 6.3V x2, dual 115V/230V | |
| Vintage 760 VCT | USD 39.99 | 760 VCT, 6.3V + 5V |
Where each product wins
Both transformers list a US country of origin. Choose the Antek AS-1T250 if you want a new, named transformer with flexible secondary wiring. Choose the Vintage 760 VCT if you are restoring vintage audio/video gear and want a lower-priced transformer with a specific vintage output set.
Product notes
Antek AS-1T250 - Tube Amp Power Transformer (100VA, 250V x2 & 6.3V x2)
The Antek unit is the more fully specified of the two. It is listed as new from Antek Inc with part number AS-1T250, and its 100VA toroidal design gives you two 250V secondaries and two 6.3V secondaries. The independent outputs can be wired in parallel for more current or in series for a center-tapped higher voltage, which is useful when shaping a power supply around a specific amp. It also includes heavier-gauge wires, a static shield, a magnetic shield, and compatibility with 115V or 230V at 50 or 60Hz. Its higher listed price is the main trade-off, but you're getting a new component with a clear secondary layout. If your priority is a build-ready transformer with documented behavior, this is the one to start with.
Vintage Tube Power Transformer - 760 VCT, 6.3 V, 5 V
The vintage transformer is the lower-priced option in this head-to-head. It is described as a high-quality unit for vintage audio and video equipment, with a 760 VCT center-tapped winding and 6.3V and 5V outputs. That combination can be exactly what a restoration needs. The trade-off is that the brand is listed as Unknown and the condition is listed as Unspecified, so you are taking on more uncertainty than you would with a new, named transformer. That makes this a choice for someone with a specific 760 VCT application in mind and a tolerance for extra uncertainty.
Final choice by use case
- For a new build or a defined amp project, the Antek AS-1T250 is the stronger match because you get a new, named transformer with clear outputs.
- For a vintage restoration, the Vintage Tube Power Transformer is the lower-priced pick, provided you accept the trade-offs.
If you want documentation and a new part, the Antek AS-1T250 is the match. If the exact vintage output set matters more than the unknowns, the Vintage Tube Power Transformer keeps more money in your pocket.
