    TSC Question(s)?

    Hey Folks, What signal form is assumed to be sent through the amp for the results of Duncan's Tone Stack Calculator and/or TSC in the web? Is it full range, white Noise, pink noise, or……? Just Curious? Gene

    Solder Repairs?

    Hi Folks, When doing small repairs to a circuit board suspected to have lead free solder, is it necessary to remove the old soder, before applying lead solder? Or will the lead solder simply displace and/or mix with the lead free stuff and form a better, less brittle joint? I'm talking about the...

    First Real Gig, SV20H/1965B

    Hey Folks, Last weekend I did my first real, full band (three piece) gig using my SV20H through a 4x10, 1965B loaded with the original 94db, G10L-35 speakers. I was actually able to get away with the amp fully cranked into it's sweet spot and not be too loud, even without using an attenuator...

    Ampeg Bass Amp Knowledge?

    Hey All, We have both an SVT Classic and V-4B heads and love them both. They can both sound nearly identical, at low to medium volumes, when using the same mid center frequency settings. The down side here is that we prefer 450hz mid center of the #2 position of the SVT Classic, over either the...

    '70, 1960B, Refurb And/Or Sell?

    Hey Folks, I have a bit of a conundrum. I've got a '70. 1960B cabinet in need of some TLC. I also need to thin my herd. PROS: > It has all the original metal handles and top caster cups. > Has original cloth with the damage shown. > Original plywood back panel with original metal jack cup. >...

    Is The SV20H Honeymoon Over?

    After more than a month of intimate daily sonic shenanigans and bouts of late night tonal debauchery, I've hit a disturbing snag with my gloriously sexy SV20H! Let's first bear in mind that I've been plugging electric guitars into various amplifiers for a little more than a couple of minutes now...

    I'm Drunk And

    I'm drunk and playing my LP Firebrand and Strat, by myself, through my SV20H at full power, '72 greenback loaded 1960B, attenuated to -7db ( @JohnH style), with a Lexicon MX300 in the loop as my second guitarist and the tones, sounds, licks and new hooks inspired are astounding. May everyone...

    NAD - SV20H

    My new SV20H showed up on Saturday and is absolutely stellar in every way I had hoped. I expect a long, enjoyable honeymoon, filled with tonal debauchery and musical mayhem! Details and pics, when I can pull myself away long enough to do so! Right now, I'm determining the best of my many...

    Cable Wiring & Measurement?

    Didn't want to glom onto and/or hijack any other "cable" threads, so…..? I have some questions concerning using microphone style cable, with two center conductors (black/white) and shield for instrument cables, how best to wire them and how to test for capacitance and/or impedance. A> Is there...

    "SOLD" LANEY AOR PRO TUBE LEAD 100 "SOLD"

    If you are looking at this, know what it is and like them, you want this one! For those who don't know it, this is generally a heavily hot rodded (from the LANEY factory in the UK), 100 watt Marshall JCM800/2203. This thing is a monstrous beast, but the MASTER VOLUME works so well that you can...

    Why Always "More Gain?"

    Hey Folks, I'm a little confused by the tendency by so many folks to always be looking for "more gain" in their amps! I get the desire for "just a little bit more oomph" to get into certain types of feedbacks and harmonics, but past a certain point, the sound becomes just an overly compressed...

    Effects Loop For Class 5?

    Hey folks, I've searched everywhere I can and not found anyone who actually installed and effects loop in a Marshall Class 5 amp. I've found many armchair discussions of how it likely wouldn't work well, given that so much of the overdrive characteristics happen at the power tube. I still think...

    Inventory Spreadsheet?

    Hi Folks, I don't often frequent this sub-forum but have a general dilemma and questions. I have tons of guitars , amps, musical gear, etc. and I'm scheduled to go "toes up" fairly soon. :eek: I'd like to provide a complete inventory for my wife so that she understands what I have and what it is...

    Good 12AY7s?

    I have an old Baldwin branded (I think Sylvania) 12AY7 that sounds fantastic in V1 of my 5E3 Deluxe clone. A little noisy on occasion, but I'll deal with that until it finally dies! I've tried most of the current production versions and they all sound like Doo-Doo in that position, by...

    Frequency Spectrum Analyzer?

    Hi Folks, Maybe I'm being dumb here? It seems that a handy tool to have, along with a frequency generator that can put out white and pink noise, would be a simple, cheap frequency spectrum analyser? I'm not thinking of super high tech labaratory grade stuff, but just something to view the...

    Completed JohnH Attenuators?

    Hey Fine Folks, The Simple Attenuator thread has become so lengthy that it is difficult to ascertain how many successfully completed builds there are of the fantastic @JohnH attenuator design. :thumbs: I'm starting this thread with the intention of showcasing all of these great builds. It is my...

    Filament "0" Volt Center Tap?

    More of a "theoretical" question than anything else. Without electrically "elevating" the filament center tap, where is the best place to connect this "center tap" of what seems to be the "dirtiest" unfiltered AC circuit to the rest of the "0" volt system? At first glance, it may seem...

    KT66 & Cathode Bias?

    Has anyone here ever used KT66 tubes in a cathode bias configuration? I've not yet noticed such a use. The reason for the question is brain storming (maybe brain "farting") a JTM 45 style build. My thought is to build a JTM45 style amp, but centered around having the option of utilizing KT66...
