In fact, the Peavey Classic 50 is a classic of the Peavey range, following the classic circuit design of 1991, and with the Peavey Classic 50 410, the manufacturer from Meridian, Mississippi offers the 50-watt classic sound in combo format with four 10-inch Peavey Blue Marvel loudspeakers specially matched to the amp. The 2-channel circuit consisting of normal and lead channel offers the full program from clear cleans with a lot of headroom to tugging sounds of hard rock and metal. Last but not least, there is also a footswitchable reverb effect and an effect loop for looping in effects between preamp and power amp.
Normal & Lead ChannelThe core of the Peavey Classic circuit is its two-channel design with separate gain controls for both channels. The Normal Channel offers everything from distortion-free clean and light crunch sounds, whose preamp saturation depends on the channel's Normal Volume control. If the channel switch is set to lead, however, the distortion of the channel can be adjusted via two separate pre- and post-volume controls. Using Pre-Volume, the distortion level can be adjusted by the preamp level of the lead, while the post-volume determines the volume of the channel. Thanks to the master volume, both channels can ultimately be opened wide even at lower volumes. Effect Loop & Peavey Blue Marvel SpeakersSlightly hidden on the back of the Classic 50 410 Combo are the serial effect loop connectors. Using the send and return jack, effect devices such as delays or modulation effects can be switched between preamplifier and output stage.

So I am 106 pages into the 'eminence speaker' monstrosity of a thread and I keep reading over and over about such and such speaker will sound good on amps with fender type circuits or on marshall type circuits or vox type circuits.So what type of circuit is a peavey classic 50?Im talking about the modern classic 50 - the one that comes in 2x12 or 4x10 not the 70's model 'Peavey Classic' that is a hybrid design.Can someone clear this up for me? I believe I have read that the Classic 30/50s are based off the Vox AC30 design. Is this true?This knowledge would maybe help me interpret the huge eminence speaker thread. Thanks in advance. I think there are some similarities to a vox but it stops at 4-EL84's.They don't sound anything alike and the Peavey has all kinds of typical peavey stuff like pre and post gain structures,reverb and it's fixed bias.It runs the power tubes at high voltage and throttles back on the current so they live.An AC30 is cathode biased.Really,the only thing it shares with the AC30 is it's 4-EL84 power tubes.Not a bad sounding amp,but it cooks the tubes,has undersized transformers,uses DC heaters and is a circuit board nightmare. Click to expand.Thanks for the info.The quote above sparks 3 questions:Cooks the tubes? Which ones specifically?
Peavey Classic 50 Specifications
Preamp tubes, I assume? Anything I can do to minimize this?Undersized Transformers - does this mean that a transformer upgrade could be a good 'bang for the buck' upgrade?Circuit board nightmare: This makes it hard to mod, I guess?
The blue guitar page has lots of common classic 50 mods and I was thinking of trying one myself (the simple one that puts the lows back into the drive 'channel') would I be better off taking this to an experienced tech? My experience is limited to building pedals (and yes I know all about draining the caps)Thanks for your info.Brian. Most people who mod / build amps start with amp kits because I it is usually PTP construction with clear instructions and visual layouts. I would suggest building a kit first to build your confidence then move to building amps without a kit getting support from a forum like 18 watt.com. I would build a simple fender circuit or marshall 18 watt TMB before you attempt say a SLOCOLONE.
Then I would look into moding your main amps that have PCBs. You will find that tube amps are simply devices. The real talent lies in designing unique circuits. Good luck if you take the plunge it can get additive.
