This Dynakit ST-70 amp is fairly dirty from sitting in storage for so long. I have no idea when it was last used. It’s been modified with some gold RCA connectors, and there may be more mods under the chassis. Please note that the EL34 tubes that are included are not Mullards, but rather National that claim to have been made in Germany. My guess is that they were made in Russia. No GZ34 is included, nor is a cover. This one will make a great parts unit or candidate for restoration. This piece of equipment is believed to have not been used in years (possibly decades). It will almost certainly need some level of service. This may include: replacement of electrical components (such as capacitors, resistors, diodes, tubes, etc), cleaning of controls, alignment, and so forth. If you’re not qualified to do this work yourself, we’re happy to provide you with a list of qualified technicians available for hire. If you prefer one carrier over the other, please make that request when paying for the item. Rest assured, you’ll receive your item in excellent condition!
