One enhances the reverb.  \u003cbr\u003eUpgrading these specific ceramic caps increases clean sustain, harmonic complexity, and overall 'oomph' of the amp, while reducing the 'ice-pick' factor. The reverb also gets more depth and detail. We use a very tasty, selected NOS caps for the reverb and a Jupiter for the vibrato channel enhancement.  \u003cbr\u003e\u003cbr\u003ePremium overhaul kits include high quality\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eF\u0026amp;T filter caps\u003c\/strong\u003e.  Preamp tube cathode bypass \u0026amp; bias caps are high quality Nichicon \u003c\/p\u003e\n\u003cp\u003eWe use only the highest quality\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e1\/2w carbon resistors\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003efor the signal path \u0026amp; circuit board.  Key locations in the circuit have measured \u0026amp; MATCHED PAIRS of resistors – vital to optimum performance and minimum phase cancellation.  Flameproof metal oxide resistors for the power and bias supply.  \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Jupiter Condenser signal caps also available to replace and missing blue molded caps!!\u003cbr\u003e\u003cbr\u003e\u003c\/strong\u003eIf your blackface Princeton Reverb has the 'Brick Red' signal caps, this option to replace them with Jupiter caps is HIGHLY RECOMMENDED!!  Takes your PR a LOT closer to true blackface tone!  A NOS reverb upgrade is also included in the Jupiter upgrade.  \u003cbr\u003eIf your PR has the BLUE MOLDED CAPS already, do NOT get the Jupiter upgrade!!  NEVER remove the BLUE MOLDED CAPS!  If you DO have the blue MOLDED signal caps, the Premium kit that replaces two ceramics in the signal path is recommended.  \u003c\/p\u003e\n\u003ch4\u003eADDITIONAL ITEMS TO NOTE:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCopies of the original blackface schematic \u0026amp; layout for your amp are included \u003c\/li\u003e\n\u003cli\u003eReverb in both channels mod included in kits for amps with reverb and 2 ch!\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstructions\/parts for adjusting the bias included (where applicable)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"vintagefenderamprepair.com","offers":[{"title":"Standard","offer_id":46914051932311,"sku":"bf_oh_prinec_rev_STD","price":120.0,"currency_code":"USD","in_stock":true},{"title":"Premium: Incudes Ceramic Signal Cap Upgrade (NOS)","offer_id":46914051965079,"sku":"bf_oh_prinec_rev_CER","price":135.0,"currency_code":"USD","in_stock":true},{"title":"ADD Jupiter signal caps","offer_id":47981582712983,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2325\/2729\/files\/IMG_7420.jpg?v=1783370437","url":"https:\/\/vintagefenderamprepair.com\/products\/princeton-reverb-blackface-overhaul-kit-copy","provider":"VintageFenderAmpRepair.com ","version":"1.0","type":"link"}
