With Cabinets/Cages/Covers/Consoles enclosures : cabinets, metal cages and Console Enclosure hinder air-flow and as such your tubes will only generally last 1/2 as long. So we suggest operating this Sherwood S-5000 outside of its cabinet for daily use. We also suggest using all tube audio units in operation without covers. Additional we suggest using a high quality computer fan behind these tube type units to dissipate vacuum tube heat (just visit your local Computer repair/parts store many have fans available for low cost). In 2025 a NOS vintage tube complement(12 Premium tubes) in these units cost was as much as an unrestored unit with average/user supplied used tubes. A Light that burns twice as bright(twice as Hot without ventilation) burns 1/2 as long’. Please Follow this suggestion and Your tubes will love you!

Changed old caps to NOS Polyester/Mylar’EM’ CDE tone caps, Upgraded the Power output By-pass caps from 0.068 mF 400VDC 20% to 600VDC 10% to upgrade power reserves with low tolerance to potential failure going forward. Replaced AC line Chord to a new heaver duty 2-prong(Chassis is Grounded). Cleaned all Tube Sockets, Switches, Pots & Contacts with CRC QD electrical contact cleaner then Deoxit5 electrical lubricant. Pulled and replaced all Vacuum Tubes with either NOS or TV7D/U tested Strong & Balanced replacements high quality replacements.

Be Patient with the Setup & Reinstallation of all the 12 VACUUM TUBES. Carefully unpack the unit and the tubes. Remove the metal cover. Insert the tubes in there proper sockets. Connect your Speakers wire pairs to the matching 16/8/4 ohm screw connectors on the back panel with Proper Phase’+’ =Red=hot connect to either 16/8/4 ohm back panel screw and the other wire to’-’=White or Black=COM screw on the back panel. NEVER turn on AC Power or Operate any Amp/Integrated Amp or Receiver without a pair of Speakers connected to the correct Ohm reading of the speaker. (This is called speaker loading). If you turn on any amp without speakers connected(a Load) you might damage the Output Transformers. Then connect your input devices : CD/Tape and any other Line Level device and/or your turntable to either High-level or Low level(phono cartridge) into there indicated back panel rca inputs. Then plug in the line chord and turn the power on this integrated amp. THANK YOU FOR LOOKING!
