Changing Tubes, Warranty and Service Info

CHANGING TUBES:

Always use caution when changing tubes. The power switch on the ampliﬁ er should be turned off and the power cable unplugged from the source.

CHANGING POWER TUBES - The tubes should be cool. When changing the power amp tubes slip off the spring- loaded silver tube retainer and carefully work the tubes out of the ceramic socket by pulling down while rocking the tube slightly and gently. When re-installing power tubes, note that both the tube base and the pin positions are “keyed” to the socket. Make sure that you seat the tube base properly in the socket and carefully push it tight into the socket. Conﬁ rm that the BIAS SWITCH is in the correct position for the type of power tubes being used.

CHANGING PREAMP TUBES - The tubes should be cool. Each preamp tube is secured with a special tube retainer that keeps the tube seated properly and also helps to counter-act unwanted tube micro-phonics. A small Phillips screwdriver will be needed to unscrew the round tube retainer. After this retainer has been removed, rock the tube slightly and gently while pulling up on the tube and remove it carefully. When re-installing preamp tubes, note that the pin positions are “keyed” to the socket. Make sure that you seat the tube pins properly in the socket and care- fully push it tight into the socket. Reattach the round tube retainer. Make sure the rubber grommet inside the tube retainer securely holds down the preamp tube.

Important note: It is critical to the optimum performance of the El Diablo 60 that a premium high grade 12AX7 tube is used for the ﬁrst tube in the signal chain (located directly behind the input jack). This tube must be selected for its very low micro-phonic content in order to minimize high gain feedback or squeal in the Hot channel when using maximum gain settings at high volumes.

OUTPUT TUBE BIAS – Refer to the Tube Bias Section listed previously in this owner’s manual.
