The XP-60 was one of Roland's flagship digital Workstation Synthesizers. With extensive professional features, superb quality PCM sounds, sequencing, effects and more, the XP-60 could be the only synth you may ever need! Compared with other XP- synths, the XP-60 is almost the same as the XP-80 except that XP-80 has a great 76-note semi-weighted keyboard whereas the XP-60 has a standard 61 note keyboard.

Like the XP-80, the XP-60 offers up 64 voices of polyphony and can send on up to 16 MIDI channels simultaneously. The sounds are all digital in nature and sound pretty good too! Though its strengths are the emulation of acoustic instruments, it can create convincing synth-type sounds too. It comes with 16MB of ROM sounds, but there's room for up to four 8MB expansion boards that add Orchestral, Techno, Vintage Synths, World, Bass & Drums and other instrument sets (from the SR-JV80 expansion series).

Bringing up the 'Workstation' end of the XP-60 is a full-fledged on-board MRC Pro sequencer. With a 60,000 note capacity, 100 patterns, and 1 song position - you can create songs, patterns, loops or phrases with relative ease. Other features of the sequencer include Grid, Groove or Shuffle quantization and a built-in disk-drive. A great Arpeggiator is also available. High quality internal effects are provided such as Reverbs, Chorus, Delays and many great multi-effects. There are also digital filters (4-pole, 12dB/oct, HP, LP, BP, Peak) and a ring-modulator for analog-synth type effects, perfect for dance and techno music! A Modulation-Matrix provides up to two LFO-effects for adding motion and life to the sounds. In addition, there are 6 sliders for real-time control.

In a nutshell, the XP-60 is a pure digital synth. Its sounds are virtually the same as the JV-1080, JV-2080, XP-80 and XP-50 synthesizers. And the XP-60 makes a great all-in-one Workstation for any musical application. For a digital instrument, the sounds can be surprisingly expressive and the XP-60 is not reserved for any particular musical genre, other than top-quality music!

Hi-Fi stereo amplifier with 8Ω output. Semiconductors: 3 ICs, 36 transistors and 21 diodes. Tuner, two magnets and a magnetic turntable can be connected to it. There is a headphone jack on the front panel. Balan, high and bass control and volume potentiometer are located on the front panel. The push buttons can be used to adjust physiological volume, mono-stereo switch, high and low-cut filter. Below the input selector buttons. The display is a two-line VFD panel. Next to it is the "Mute" button, which reduces this volume by 10 dB.
Frequency response: 10 to 40,000 Hz. Bandwidth: 20 to 20,000 Hz. Signal to Noise: From tape and tuner inputs: ≥58 dB; turntable input: ≥50 dB. Harmonic distortion: 0.06%. Intermodulation distortion: 0.2%. Transduction attenuation: 1kHz for tuner and tuner inputs: ≥50 dB; turntable input: ≥40 dB. 10 kHz for tuner and tuner inputs: 40 dB; turntable input: 30 dB. Output power: sinusoidal: 2x30 W; music: 2x50 W. Power consumption: max. 160 W.

Videoton's second generation (RT-402) high-fidelity Hi-Fi tower amplifier. Additional features of the tower include Videoton RT 6303 S tuner, Akai AP-Q310 / C turntable, Akai CS-F210 tape recorder, VT DC 2550 speaker and SA7 stand.
Its predecessor is the VT EA 6380 S, which has changed a lot. Interestingly, when you touch the buttons, the electronics mute the amplifier so there is no noise or bump on the loudspeakers when switching on. Its amplifier includes BD809-BD810 high-purity transistors, but the same can be said of the other semiconductors used in the final phase. Despite its active use, the last bolt is in its original, flawless and scratch-free state, making this amplifier even more special.

Special Features

  • removable front grille

Today I pulled the woofer on one and took a look around in them. The big surprise is that the woofer has what looks just like the normal aluminum frame that I'm getting used to seeing on Cantons but actually it's a plastic frame! It looks like it might be some kind of glass reinforced plastic, but plastic nonetheless. The speaker box is also a 2 piece plastic cab with the front baffle being the 2nd piece and is removable, being held on with 6 screws.

The caps are the typical Canton caps made by Wego and don't have any value markings other than 23vac, just part numbers. The part numbers for everything are as follows:

Tweeter = 2746
Woofer = 1368
Cap (tweeter) = 3779
Coil (tweeter) = 2097
Cap (woofer) = 1228
Coil (woofer) = 2862
And 2 resistors, 12 ohms and 150 ohms.

I'm putting a list together of the cap numbers from all the different Canton speakers that I and some friends have and will be writing Canton to ask if they can identify them. I'll post when I get an answer just to put it on record. Wego apparently specializes in producing OEM caps etc made to spec for the end user. And I've already found out that pulling and measuring a cap with an LCR meter doesn't help much because some (most?) of the caps are made to some non standard values, such as what I found in a CT 80. A cap with PN 1615 measured 139.9µF when I pulled it. I found out in a German HiFi forum that that cap has an original value of 120µF. So this is turning into an interesting bit of research.
