Product Reviews
I put this tube in the PI position in a '69 Drip-Edge Deluxe Reverb that has been blackfaced. This, along with a set of NOS JAN Philips 6V6's and a Tung-Sol reissue 5AR4 pretty much gives me the perfect tone and performance out of this amp.
Nice even frequency response. Helps to lower the gain as opposed to a 12ax7. I put the 5751 in the pre-amp section of a Monoprice (Stage Right) 1x8 5 watt tube amp. I also upgraded the power tube from a JJs to the Tung-Sol 6V6 GT. The two upgraded tubes make this amp really shine.
Helped to clean up the normal channel on a 65 Fender Deluxe Reverb to make pedals more useful.
Nice tone for V1 & V2 in Custom 57 Bandmaster RI but was microphonic. Hopefully the replacement will be better.
