These Manley Snappers were the fortieth pair they made. They do not have the triode switch, which Manley actually discourages anyhow, but it does have the option for 600 ohm inputs. That option is great for pro audio applications and long interconnect runs. They are in good shape, and come with nearly new tubes in all positions. Less than 20 hours on the whole set of tubes: new production Tung-Sol 12AT7, GE 5687, Electro-Harmonix 6CA7.
The power supply capacitors were replaced with OEM parts exactly. There was nothing wrong with the original caps, but I did it as a preventative measure. They are very expensive to replace, it was over 600 dollars for both monoblocks. The new caps did not change the sound of the monoblocks, so the ones that were replaced were totally fine. Under 20 hours on the new PS e-caps.
The six MultiCap film caps in the each monoblock were replaced with Mundorf Silver/Gold in Oil in exactly the same value capacitance as the stock film caps. I initially thought there was little change in the sound, but after breaking in they definitely have made an improvement.
I will split PayPal fees and will only charge actual shipping amount. I am happy to use your shipping account so you can be sure it is the correct amount.
If you are curious, the reason I am selling them is because I bought some horn-loaded speakers and I am trying SET next. Thank you for looking and reading the ad!

Features and Specifications
100 Watt partial triode (UltraLinear) EL-34 output stage is tolerant of a wider variety of output load conditions than pure pentode. Precise and balanced signal path from input to output. Circuit self-balances with either single-ended or balanced inputs. [Don't let either speaker terminal contact chassis, earth or any other ground. Switch-selectable RCA unbalanced inputs, or XLR balanced inputs. RCA jack input impedance about 330 kOhms, XLR 15 kOhms. If one input is not occupied, the input selector switch may then be used as a poor-man's MUTE switch. Handy for checking the bias, swapping input cables, etc.. Input Sensitivity RCA jack: 750 mV RMS for full output into 5 Ohms Input Sensitivity RCA jack: 71 mV RMS for 1 watt output into 8 Ohms Input Sensitivity XLR jack: 1.5 V RMS for full output into 5 Ohms Overall voltage gain RCA jack to Output: 31 dBu, or about 32 volts per volt. Signal to A-weighted noise ratio on Humberto's bench is about 110 dB. Damping Factor: 4.7 All-balanced amp topology keeps B+ voltage variations from degrading the performance of the input and driver stages. This technique can help make a push-pull amplifier very revealing of signal detail, in part by canceling power-supply-related perturbations and increasing signal-to-noise ratios. Portly 180 Joule energy storage reservoir in the main B+ supply channel for explosive transient response and athletic musical stamina. Also reduces B+ fluctuations due to varying current demands of output stage. Wideband transformerless balanced input with bridged 15 kOhm input impedance. Balanced input sensitivity may be selected by changing one resistor to suit whatever operating level may be required. 0 dBu, +4, +8, etc... If desired, the user may safely ground either pin 2 or 3 for single-ended drive of the balanced XLR input... [Be careful NOT to drive pins 2 and 3 of the XLR with a large common-mode signal, or the internal B+ fuse could blow.] Quiet DC supply for the input and driver tube filaments. Excellent square-wave response, and very low excess phase-shift with frequency. Amp actually puts out 110W @ 5 Ohm load @ 2 kHz @ onset of clipping, 117 VAC mains voltage, 3.5 amps mains current. 100 W spec: 15 Hz - 40 kHz into 5 Ohms Puts out 100W into an 8 Ohm load. Snapper unit weight: 38 lbs.
