lowrey organ amp conversion

[Ran Randle]

i virgilvdog forgot to mention that my lowrey amp has 6l6 tubes i was wondering if the 6l6 tubes should be 6l6gc tubes because i was told that 6l6gc tubes was not made in 1959 and these two 6l6 amps i have were made in 1959 . info from the seller. i purchase from.thank you for any input.

Hi, good luck with your lowrey amp. The difference between the 6l6 and 6l6gc: "The "g" version is not up to the specs of the "gc" and may well redplate and burn up in a circuit intended for GCs. IE, the G has a 19w plate, the GC has a 30w plate."

As posted earlier, as is these amps are just a power amp and needs to be driven with a preamp/line level signal. If you are plugging an instrument straight into it you won't get much volume.

lowrey amps

lowrey power amps 6l6gc they were hook through preamp & computer it is some thing wrong with the output power. i replaced filter capacitors , grid resistors, cathode 47k resistor , tubes are used from ebay. maybe i need to change all the resistors. or try brand new tubes. that is expensive. i would had bought new ones at first if i had were sure that was my problem this is my first experience with tube amps.
