EQP-WA: Vintage Tubes vs Stock Tung-Sols

The new Tung-Sol tubes get a lot of praise all over the internet. Still, I decided to try a pair of vintage tubes in the EQP-WA and wanted to share the results of the Tung-Sols against a 1958 RCA 7025 (12ax7) and 1958 Sylvania 12au7. Here is the Dropbox link to the files:

I used a wav clip taken from a website that allows the files to be freely downloaded for mixing practice. I assume this is OK. The artist’s name is David Youngs. The file is a single acoustic guitar and I used the first 30 seconds. All recording was done at 44.1 / 24 bits. The recording chain was:



Wavelab > Delta 1010LT > EQP-WA > Delta 1010LT > Wavelab



I recorded one file with the EQ bypassed and one with a slight cut at 20 Hz and 50% boost at 8 kHz. So, that is a total of 4 files for the Tung-Sols vs the vintage tubes. The original wav clip is also included. No additional processing was added. I did burn the TunSols in for one hour before the test.



I’ll reveal which files use which tubes later. One other note, the Tung-Sol tubes are physically wider than the vintage tubes and were very difficult to take out.
