Capacitors order list for Tandberg Huldra 10 -------------------------------------------- All capacitor are electrolytic type unless noted. I like to keep as many original components as possible. But for safety reason and possibly being those caps that had most stress through nearly 50 years I replace all electrolytic caps on power supply and power amp except the input coupling caps which are some special selected types compared to power rail caps with identical value. I'm unsure all 2.2µF used to block DC on inputs on each module truly are tantal type. Dielectric are unknown and it might be better to call them drop capacitor. They do have similar mushroom shape and dipping process into liquid insolation layer as typical tantal does. Anyway, they are part of the sound and we better keep the originals if possible. If replaced try film capacitors. NOTE: Several 22µF values have 47µF mounted on PCB on newer revision without schematic being changed. Power Supply #41150 C1006 - 4700µF 70V (*) C1005 - 220µF 50V C1004 - 10uF 100V (35V) C1003 - 22uF 40V (47µF original on PCB) C1001 - 100µF 50V (feed stereo indicator bulb)(**) * rectifier and fuse seem to hold if increased to 10.000µF which give better ripple measurement and bass performance ** Tantal on PCB but not on schematic parts list Power Amp #41115 takes 61V from PSU C725 - 470µF 63V possible has to do with power mute circuit Left: C701 - 22µF 63V input signal C705 - 22µF 63V C707 - 47µF 100V C709 - 250µF 40V C719 - 4700µF 70V* * manual list 40V as minimum voltage for this cap later H10 have 3300µF same as TR-1000 Right: C702 - 22µF 63V input signal C706 - 22µF 63V C708 - 47µF 100V C710 - 250µF 40V C720 - 4700µF 70V * manual list 40V as minimum voltage for this cap later H10 have 3300µF same as TR-1000 RIIA AMP #41201 35V Left: C503 - 10µF 25V C511 - 100µF 25V C513 - 100µF 25V Right: C504 - 10µF 25V C512 - 100µF 25V C514 - 100µF 25V RF Board #41160 35V Left: C551 - 2.2µF 35V input signal - Tantal C555 - 50µF 40V C557 - 10µF 25V Right: C552 - 2.2µF 35V input signal - Tantal C556 - 50µF 40V C558 - 10µF 25V PreAmp #41150 35V Left: C605 - 2.2µF 100V signal C609 - 10µF 100V signal C621 - 10µF 100V signal C623 - 2.2µF 100V signal - Tantal C625 - 50µF 40V C635 - 2.2µF 35V signal - Tantal C637 - 100µF 25V signal Right: C606 - 2.2µF 100V signal C610 - 10µF 100V signal C622 - 10µF 100V signal C624 - 2.2µF 100V signal - Tantal C626 - 50µF 40V C636 - 2.2µF 35V signal - Tantal C638 - 100µF 25V signal
