Dr Z Maz 18 SRV Option

Product Details

It's no secret that Stevie played his amps cranked and preferred a little cleaner sound from the front end allowing you to hear more power tube breakup. Well, this works really well with the Dr. Z amps too! This kit uses a JJ 5751 for V1, a standard JJ ECC81 to replace the 12AT7 along with three ECC83S's one being current balanced for the phase inverter in V5. The kit includes a JJ GZ34 rectifier tube and a matched pair of JJ EL84's for power.

Mike recommends a JJ gt #6 for power but since we have 30 different grades of the JJ EL84's and we know where the bias point is on these amps, just let us know in the comments section if you're looking for an early breakup, a moderate breakup or a later breakup for more headroom in which case we will choose the coolest grades we have available for the power tubes.

The ECC81 is located in V3. The Balanced ECC83S is located in V5 closest to the power tubes and the 5751 is located in V1.

Combo amps are very hard on tubes because of vibrations which can cause tube rattle with any brand of tube. If your amp is the combo version and you play by yourself in a quiet environment or record with your amp you may want to consider using the EuroDamper tube damper rings for the two EL84’s and the GZ34. These are available in the "Related Products” tab as a set of two small dampers and one large damper for the GZ34 and will greatly decrease tube rattle. ** Note; the wire tube retainers will not fit all the way over the damper rings.

These amps are cathode biased, there is no bias adjustment to be made. The amount of clean headroom you’ll get from the power section is somewhat dictated by the grade of power tube used. A cooler grade of EL84’s will give you more clean headroom, whereas a warmer grade will give you earlier breakup. If you order online, leave us a note in the comments section letting us know your headroom preference (max headroom, middle of the road or early breakup).
