I want to upgrade my 1978 Polk Model 7A's and would like to verify my parts list. I listed parts from two websites, one carried ClarityCap the other Sonicap. Also, please let me know if there is anything else I should do to these speakers to improve their sound quality. I bought them ~2 yrs. ago and when compared to my Polk Model 5's (original owner, 1982) the 5's sound cleaner in the high and mid range. I am going to take them to a local shop to ensure that it's done correctly (vs me **** it up). Any help is very much appreciated, TIA!!!
These are all from Madison Sound Speaker Store.
1. ClarityCap 12 mfd CSA CopperConnect Poly Cap 250V or ClarityCap 12 mfd PX Range Polypropylene Caps?
2. ClarityCap 33 mfd CSA CopperConnect Poly Cap 250V
3. Mundorf 4.7 ohm Metal Oxide Film Resistors or Mundorf M-Resist Supreme 4.7 ohm Resistors?
These are from Sonic Craft. The voltages are all higher than the original parts per my research. Is this a problem?
1. Capacitor Gen I Sonicap 12 uF 200VDC
2. Capacitor; Gen I Sonicap 34 uF 200VDC
3. Resistor? Gen I Sonicap 4.7 uF 200VDC
