Default Went to the toy shop last week....

Dennis has been really tweaking the Inspire 45....

It has an amazing amount of detail, plus really solid woofer control/damping for a single tube triode amp.

Dennis obviously is a fan.....

I am certainly enjoying my 45 Fire Bottle!

What do we have on the floor?

I believe the amps on the floor are two refurbished/modded single ended EL84 stereo console amps, the Copper triode strapped gas regulated PSE prototype,
Dennis's personal FireBottle, and on the coffee table is a pair of PSE mono's...Straitwire

Do you remember your post about issues with the 80 rectifier? My LP27a was acting up and after using Deox and Pro Gold on all the sockets all is well. Dirty sockets were the problem not the 80.

Cleaning sockets will be on the maintenance schedule going forward.

Thanks for that reminder. I have found that the 27/56s need cleaning to remove noise before. As I recall my 80 issues had to do with dead sections. Not sure cleaning would have solved that but maybe the pins had just lost complete contact. Next time I will double check.

My 80 issue was a dirty socket in the preamp. I got some bristly pipe cleaners at Walgreens and they worked great with Deox.

Have there been radically different versions of the PSE amps produced over the years? If so, what were the differences in sizes, tubes, transformer layouts?

As I understand it there have been2 versions of the PSE. The first, like mine, is on the large chassis running deep. A symmetrical layout with Rect in rear, driver in front surrounded by output tubes. This was designed around the KT-88 tube, 6sn7 and the rectifier was not a rectifier but a IIPS mod. It uses diode rectification. There were a couple of PSE that went out before mine w/o the IIPS upgrade in that DH developed that around the same time. I remember a picture of a chassis with two rectifier sockets so someone out there has tube rectification and the IIPS. Second gen PSEs are layed out with the chassis running long ways side to side. These have (3) gas regulator 'tubes'. There is one of these for sale at the moment on several sites. As I understand the PS with the gas regulators is the only difference but you know how Dennis rolls. Always changing things up.

When getting mine I told Dennis I had not found a KT-88 I liked so no need to supply any. He supplied GL KT-77s instead and said it seemed like he had designed the amp around that tube they ran so well in it. As always system determinate.

I am sure Tony can say more.
