Selling a very nice Grundig NF 20 EL 84 tube amp. This 2 channel amp is in very good to excellent condition. It has been freshly pulled from a console and has never been on the market before. It is also untouched and completely original. It has been brought up slowly using a Variac and has no hum or other issues. She sounds lovely. Does not have the troublesome selenium rectifier but rather discreet diodes. Note to be a reliable component this should be gone through by a tech and should have all the electrolytic caps replaced. However, I know some like these original and here is one.
The tubes are all vintage Valvo made in Heerlen, NL in the early to mid 60's, They have all been tested for MU and measure as follows:
ECC83 (12AX7) I65 ⊿3H1 1200/1100 (New ECC83 tubes should measure between 725 - 1150)
ECC83 (12AX7) I65 ⊿5F4 1050/1050
EL84 (6BQ5) rX4 ⊿4B4 6050 (New EL84 tubes should measure between 3650 - 5800)
EL84 (6BQ5) rX4 ⊿4C1 6000
