Everything out yet again……just to change one bloody 'iffy pot!

One of the output tubes was duff so I put a pair of JJ KT77’s in this one…They sound really good with these!

PCB back in place.

There was also a big problem with one of the output tube bases. This needed to be changed.

The replaced bases. These are really good bases. They are “glass-filled nylon”. There are holes between each pin which greatly reduces the risk of arcing. They are actually “Octal relay bases”, and they have an extra two flanges for the relay retaining clip to fit too. These extra side flanges make them a very good & sturdy base for tubes. Some years ago I bought a batch of 200 of these, I wish I could find the same ones now as I have only about 10 left!

They are also the PCB mount type. However, I don’t have a problem wiring to them….as can be seen above.

All finished, and looking pretty tidy/neat too!

RAY'S EMAIL REGARDING HIS LANEY:


"Hi John.

Pleased to report that I have given the amp a good testing now with a big range of guitars. The Strat sparkles, the Tele spanks and the Gibson's all sing and grunt like good 'uns!

As well as your obvious electronic repair skills, the adding of the JJ KT77's has really improved this amp! Many thanks for everything. I will speak to you soon regarding the Burman.

Best Regards, Ray."
