Vintage Tube Amp

This particular set tests very strong and are closely balanced. The print on these tubes is extremely fragile and will easily rub off, most has already rubbed off on one of them, special care was taken not to rub off any more while testing (the one that still has the most print is the stronger of the 2). The tubes’ test results are displayed in the photos (New 12AX7 Spec 100% = 1,600 Gm). See the photos for physical / cosmetic condition. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.
