καλησπέρα, έχω ένα ματσαρισμένο σετ 83άρες ( 12AX7/5751 ) NOS General Electric, ... έχουν παίξει γύρω στις 80 ώρες και τις δίνω 40 ευρώ ... είναι πολύ καλή περίπτωση αν έχεις υπερβολικό gain στο προ σου ...

5751
This is the "milspec" version of the 12AX7, but is also slightly different. The 5751 has the same plate resistance as the 12AX7, but the gain factor is only 70 compared to 100 for the 12AX7. The 12AT7 also has a gain factor of 70, but since the plate resistance is different, the 5751 is closer to the 12AX7. The older "real" 5751's have extra thick mica spacers and extra support rods to minimize microphonic response. 5751's also have matched triode units. Late versions produced by Philips/ECG don't have the extra support and don't perform as well as the older 5751's.
