lawriemacmillan Posted February 25 Share Posted February 25 (edited) **SOLD** This incredible amplifier has been at the heart of my high headroom rig for years (coupled with a Aguilar DB680 preamp), and has always remained in a rackcase, so is still in great condition. It is heavy, so an ergonomic case does help. Official specs: The Hellborg power amps are set apart from other amps by the fact that they use a powerful output transformer at the speaker output of a solid state power amplifier (such transformers are normally used to match the impedance of the speaker output stage of tube amps). This is done to achieve the warmth and presence of a tube amp while maintaining the clarity and fast attack of a solid state design. The Hellborg Mono Power 500 has an output of 500 watts, the output impedance is selectable (2, 4 or 8 ohms). Power Requirement : 230 V Technology : Bipolar Power Amp with Speaker Output Transformer Power Output : 500 watts Input : ¼”, 0 dB Outputs : ¼” and Lockable Coaxial Speaker Connection Controls / Switches : Level with clip LED Power (On/Off) Voltage Selector : (115 / 230 V) Ground / Lift Output Impedances : (2, 4 or 8 ohms) Weight : 41,9 lb (19 kg) Dimensions (W/H/D) : 19" / 2RU / 15,6" (370 mm) Case not included in price. Please get in touch to discuss posting within the UK. Edited March 5 by lawriemacmillan 5 Link to comment Share on other sites More sharing options...

three Posted February 25 Share Posted February 25 According to my tech, the most incredibly over engineered amp he’s ever seen. Certainly not the lightest and a tone all of its own. I’ve had a few of these and I’m just selling a stereo 250. Pretty unique 2 Link to comment Share on other sites More sharing options...

I like that there was a power amp created with bass players in mind, as an alternative design to the huge Aguilar valve offering 1 Link to comment Share on other sites More sharing options...

I had also been on the lookout for one to pair with the Mono 500 for using with my electro acoustic bass. I'm having a hollow body 6 string being built for me and would be nice having a high headroom transparent amp... Link to comment Share on other sites More sharing options...
