Interesting Laney amp from between the Klipp and AOR Pro Tube amps. She is an interesting design with a lot of gain. A bax tone stack and separate mid control then an Ultra Linear Power amp using 4xEL34. I will attach the schematic for those interested. She sounds great with real nice preamp distortion and a great loud tight power amp. She needed new output tubes a new power transformer and caps replacing.. Really love this rather rare and interesting full on Rock amp! Not sure why they ended up going back to a Marshall style design.. probably the marketing guys..

 

As she came to me..

Wow dusty or what!

Great simple styling

 

 

Massive power supply caps with no marking

3xHRS tubres and one Mullard..

Power transformer the previous owner believed is an issue

 

Interesting used 5751 tubes in the preamp… as designed for 12AX7 tubes.. these are lower gain around 70 but all tested good. Matybe trying to tame the beast

Output transformer appeared creased in the windings but works fine..

 

One screw I could not get out the threaded end kept on turning…

Broke in through the mains socket and held the end with a pair of pliers all good but needed a new socket 😉

 

 

 

Quite well made PCB and when working on her none of the tracks lifted at all.

 

All cleaned up a little and ready for the bench

Caps original but rather heath Robinson paralleled up

 

New caps in place

Screen grid taken up to 1K

 

Output transformer is Ultra Linear Load of gain in the preamp for distortion!

 

neat wires lined up well with the existing holes

ready to wire up

 

all wired in nearly ready to power up

Needed to mod the bias circuit a little the 10K adjustment pot was a bit flaky this Multi turn one gave a lot more stable bias supply

On the bench with some old tubes for a try out

 

original seller

case cleaned up and 6 new corners added where the old ones had broken off. They are standerd vox corners

 

New voltage selector was required as the previous one iwas designed for a dual primary type transformer so a Marshall one was purchased

 

A couple of new switches as the old ones had dead Neons

On the bench and sounding sweet! Wow loud and great Preamp disctortion on tap

Quad of Shuguang EL34s biased up

 

Ready to go back in the case!

Base of the case in good condition with no major tears in the Tolex

 

Good to go!

 

Top switch no a mini toggle as much more reliable than the old push one installed

Ready for the back panel

Bacjk panel in place!

 

Looking good.. I like this version with no big Laney logo and the steel grill
