Electro-Voice EV 7300A
A two-channel workhorse from the American pro-audio house - conservatively rated, and the manuals survive even if the paperwork never did.
Overview
The Electro-Voice EV 7300A is a two-channel stereo power amplifier, built in the USA and sold under the Electro-Voice name. Every listing that survives agrees on that. It appears as the "EV7300A Power Amp" on Reverb, as the "Electro Voice Ev 7300A 2-channel Stereo Power Amplifier" on eBay, and as the "Electro Voice EV 7300A Stereo Power Amplifier" in a shopozz.ru listing. The model name gets written a half-dozen different ways depending on who's typing, but it's the same box.
The documentation on this amp is thin. The Reverb listing calls it "a solid workhorse of an amp!" and notes the unit was "in super clean condition." The shopozz.ru listing advertises its example as "Professionally Tested." Those are seller claims, not independent verdicts, but they line up with the general reputation these amps carry among the people who own them.
The power rating needs some care. The Reverb listing states the amp is "conservatively rated at 300 watts per channel." The shopozz.ru item title advertises "800W." These are not the same claim, and they don't reconcile cleanly. The shopozz figure may refer to a bridged or peak rating, or it may simply be a seller inflating a number for search traffic. The 300-watts-per-channel figure comes from a listing that actually describes the unit's condition and provenance. The 800W figure appears only in a title string. Treat the conservative 300 W/ch rating as the more credible of the two, and treat any "800W" claim as unverified until a manual surfaces.
The recurring problem with this model is the paper trail. No production years, no original price, no frequency response, no THD, no impedance, no dimensions, no weight, no input or output counts - none of it appears in any surviving source. A service manual and schematic do exist, listed on 838dz.com as "ELECTRO-VOICE EV 7300A功放维修手册" with a circuit diagram. That helps anyone repairing one, but a schematic is not the same as documented specs. What the 7300A actually measures, how it was wired, and when it left the factory remain open questions.
The practical upshot is that the EV 7300A is a known quantity to the people who've owned one and an unknown quantity to everyone else. It's a two-channel, made-in-USA Electro-Voice power amp, it's rated conservatively at 300 watts per channel according to the Reverb listing, and it has a reputation among sellers as a solid workhorse. Beyond that, the record is genuinely incomplete.
Collectibility & Value
No reliable price history exists for the EV 7300A. Current asking prices aren't documented in any source, and the eBay product page shows the model as "Currently sold out," so there's no active supply to benchmark against. The Reverb listing carries the title "EV7300A Power Amp, Made in USA PRICE DROP," which suggests a seller who had it listed long enough to cut the price, but the listing doesn't disclose the numbers.
The documentation situation helps a buyer a little. A service manual and schematic are available through 838dz.com, so a buyer isn't completely on their own if something goes wrong. That's more than a lot of amps from this era can say. The 7300A should be repairable in principle, even if the spec sheet has gone missing.
Common failure points, maintenance intervals, and spare-parts availability aren't documented anywhere in the surviving record. Anyone considering a purchase should inspect carefully and ask the seller directly. The "Professionally Tested" and "in super clean condition" claims in listings are worth taking at face value only after verification.
