If you require two power tubes in a push pull configuration then you would want to purchase a matched pair.

Power tubes need to be matched in order for your amp to operate properly. If you ordered your tubes from us, we can get you one tube to match your existing power tubes.

According to Mesa Boogie, if you order these tubes with "middle values" you should not have to rebias your amp.

It appears that the Fender 75 uses 6L6's.

With any retube, you may need to make adjustments to your amp depending on the type of bias it has. Your amp will either be fixed adjustable bias (has bias pot on the back of the amp) , Fixed non-adjustable bias (bias is fixed by a resistor in your amp), or cathode bias (self biasing no bias required). The manual for your amp should be able to tell you what type of bias you have. Rebiasing an amp is something that should be done by an experienced tech. Many amp manufactures setup their amps to accept "middle values" for tubes. You can request middle numbers when ordering. Keep in mind, this will not guarantee you will not have to rebias your amp.

This will safely work in place of any 6L6G tube.

I installed an Apex matched pair of these 6L6GCs in a 1964 Fender Super Reverb Amp. They biased to within one mA difference in plate current. They sounded good and should keep this old amp working for several more years.

I had a pretty good sounding '68 Bandmaster. These turned it into an outstanding sounding amp head. It was night and day compared to the old Sovtek's that were in there. But in their defense, they were on their last legs anyway. I'm very happy to have made this purchase.

Tubes are great
However, they were defective, and I sent them back
Antique electronic supply refused to replace them
I paid postage to send them in then back to me
Now I paid extra and have tubes that are bad

I purchased this tube to use in my THD Univalve (Class A amp) - it sounds great and was delivered within 4 days (to Connecticut) intelligently packed. Thank you Antique Electronic Supply!

Save your nos tubes...these JJs in matched sets are a fantastic value...and for the cherry on top order these from AES for the most outstanding service in the business...Been an AES customer for going on 20 years they never disappoint and most often exceed expectations...tube are expensive enough and there are too many shady tube venders out there...so go with a company that did the hard work for you...buy JJ tubes from A.E.S.
