Re: custom size amp cover services

Cover Amp in Ontario has done a few custom covers for me (https://www.coveramp.com/). Pierre and Nancy are a true Mom & Pop shop and prices are more than reasonable. If they still ship to the US.... Rigg Covers are made in WI and very well made, very price competitive. (https://rigg.us/custom-amp-co...

Re: Building an aluminum chassis without a break

Very nice work.I see you are using a MAP gas torch. I have tried this before but the aluminum sheet tended to melt just as the alumi-weld rods melted. May have been the nozzle I used (broad flame. What type of nozzle is that, a pinpoint flame? And what alloy is the aluminum sheet made of? Thank you...

Re: Inexpensive DVM wanted....

Agree but OP stated budget was a factor. My Fluke 179 is over 20 years old and still kicking. Inspite of 3 or 4 occasions where I applied high voltage in the resistance mode. My Chinese made Uni-T UT-58 is over 2 decades old and still working beautifully. On more than one occasion I had my friend b...

Re: baffle cleat size and wood type for 2 x 10" combo

Typically I use .75" x 1" pine with the .75" glued and screwed to inside of the cab. I also use t-nuts for the baffle and back panels' machine screws so the 1" width is needed for them.

Re: 5E3-taming the volume

First thing I'd do is ensure a 12AY7 is in V1. Fender used these for a reason. A 12AX7 provides so much gain that the volume control becomes a "fuzz" control. Replacing V1 with a 12AY7 (assuming you have a 12AX7 in there now) would help. Another thing is the V2 phase splitter, which is actually a ga...

Re: Filter cap philosophy

Radials from Nichicon, Rubicon, Panasonic, etc. typically outperform their axial counterparts from Sprague, F&T, MOD, JJ, etc.
Look for life ratings, temp. ratings and ripple current ratings in particular. As far as sound - brown caps sound best....YMMV

Re: what is the purpose of the anode resistor on output tubes
