PC backing boards
Some over two years ago I started an ODS build... for several reasons it went into a halt before last summer, but now it's time to get going again... I made the larger boards mysellf, with eyelets, and bought a set of the smaller bords from a vendor here.. these were delivered with blank backing boa...

Re: 2nd gen chassis and pcb design?
Somehow I think this "period correct" thing sometimes goes passed logic... If a "period" part is technically inferior.. why keep it? An interchangeable / detachable power cord would be an absolute benefit over the "old fashioned one.... and an absolute minor mod' to the design.. Just my 2 c's....

Re: Type of wire
Sorry, mate.. we have to agree to disagree... :wink: the Audiophools have been at this for years, with "this wire sounds better than that", "silver conductors sounds cleaner"... the list is endless... Not that I have anything against solid core from a technical POV.. my objections are mainly based o...

Re: Easy way to make a chassis
Well... that's a useful procedure.... making the tiny grooves where you want to fold is a very good idea.. steel or alu is just the same... Cheap or home made brakes will almost always have accuracy problems..... But of course... take your time, be accurate - or make a really good and accurate break...

Re: Type of wire
Solid core wire really has nothing to do in portable equipment. I agree with those suggesting teflon coated, mainly because of the higher temp's and voltages in tube based eqpt. Although I realise I may be shot down on this 8) , tonality of hook up wire is mostly imaginative, but given the fact of h...

Re: Options to replace odd cap value
I've spent my whole working life in electronics, ranging from audio to radar, with some electrooptics in between...
Gyrators has nothing to do in power supplys. Get caps at or slightly above the old value that needs to be replaced, with a suitable margin for voltage.

EVM12 cab alternatives..
I managed to get hold of an EVM12 locally, for project I'm working on... have anyone tried other cabs than the traditional reflex cab that's been around for a while... Open back, partially closed... etc ??

Re: Capacitor selection
I¨ve been following these capacitor discussions off and on for several years now. While there are certainly differences between cap types, I wonder how much is really owed to the type rather than tolerance variations, - particulrly in vintage capacitors which are mostly 10% at best, - 20% being more...

Re: A Tube Amp Doctor Tolex Glue thread (Europe)
I have feeling that those "Tolex purpose" glues are just rebranded water based contact glues..... Any quality brand contact glue will probably do the job just as well.....

Re: 120V versus 240V
Actually - given the same output power, the mag fields form the PT should have doubled, as the primary current of the PT are doubled going from 240 to 120V..n in order to supply the same amount of power.... 230-240V fully balanced for household (and amplifier) appliances are quite rare....
