Re: Morgan RCA35

Here is a picture of my old Morgan Amps RV35 aka the Reverb Model of the RCA35.
I had Jupiter Vintage Tone Capacitors in mine verses the SoZo Caps I see pictured in everyone else's amp.

Re: Soldering terminal strips to back of potentiometer..

I've noticed it done on a couple of amp builds (older ones, and not often). I've done it a few times, but I'm curious to get a general consensus on if it's an acceptable way to mount components near the pots or should the strips be mounted to the chassis? I recommend reading Aiken Amps section on: ...

Re: Vector Component Library

I've drawn some crude, but functional parts in Illustrator for doing turret board layouts. Not as nice as the stuff some guys around here do Visio, but it helps me figure out if and how things will fit. I just drew some simple shapes by looking at the datasheets - didn't take too long. I already kn...

Re: Best Wire to use for AC

I have some solid core ptfe 20awg I got from apex JR I have no doubt it can easily handle the 12o V from the IEC jack running to the switches and fuse my concern is the shielding on that wire is so thin won't that necessarily lead to increase interference created by the AC current passing through t...

Re: Best Wire to use for AC

Go 18 AWG on AC/DC Power Supply & Output and 22 AWG for everything else. Makes things a whole lot easier if your use stranded pre-tinned wire as well, that is if you're not one of those who swear by solid core wire. I recommend going with MIL-W-16878/5 (M16878/5) Type EE 1000V NEMA HP3 Type EE MIL S...

Re: Red Goop In Dr. Z & Metro Amps

I agree with John that it's used as a tamper evident seal for warranty. I worked for Musicians Friend (Guitar Center . com / Music 123 / Woodwind & Brasswind) for a few years as a product trainer, sales coach, and customer service trainer. When vendors would come in and I would get to open up their ...

Re: Vector Component Library

DIY Layout creator is excellent: http://diylc.org/ Has tube sockets, jacks, pots, etc. as standard, plus you can define, export & import symbols as XML files. Written by 'Bancika' of DIYStompbox forum, AX84, etc. (& maybe even here!) Tillydog, Thanks so much. That is a great find. I have to install...

Re: Vector Component Library

Is vector a layout app? If so, is it ported to Mac? My Definition: Vector Artwork is created in Adobe Illustrator or other CAD/Computer Graphic Creation programs; often used to create logos or drawings like you find on sites like http://www.brandsoftheworld.com . Vector artwork can be used at enorm...

Vector Component Library

Does anyone know of a vector component library of electronic parts (schematic or layout type)? I am hoping to find some scale part drawings e.g. tube sockets, potentiometers, turrets, switches, etc. If there is not anything like that out there I would like to start working on assembling one for the ...

Re: Push-Pull Without a Phase Inverter

Without a phase inverter the design has been compromised (not to say each PI has its own compromises). Field coil amp section from an 30's radio.

Re: Push-Pull Without a Phase Inverter

http://home.comcast.net/~stphkeri/magnatone_109.png Used signal from the screen of the first power tube to to the grid of the second. I built this power section into an amp once to cut down one tube. Just not enough volume, and the sound wasn't distinct enough to be cool for cool sake info here: ht...

Push-Pull Without a Phase Inverter

After reading the a post titled "Self Inverting Push Pull EL84 Amp" that you can find here: http://www.freestompboxes.org/viewtopic.php?f=2&t=15276 I recalled an article called "Push-Pull Without a Phase Inverter" which can be found here: http://www.ampbooks.com/home/amp-technology/6L6-phase-inverte...
